A 3 kg can containing a 100 g firecracker is thrown into the air. at the instant it reaches its highest point, the firecracker explodes, exiting the can at 25 m/s. The speed of the can after the explosion is 0.83 m/s.
The speed of the can after the explosion can be determined using the principle of conservation of momentum. According to this principle, the total momentum of a closed system remains constant if no external forces act on it. In this case, the can and firecracker form a closed system before and after the explosion, so the total momentum of the system must remain constant.
Before the explosion, the total momentum of the system is given by:
p1 = m1 x v1
where m1 is the mass of the can and v1 is its velocity (assumed to be zero at the highest point).
After the explosion, the total momentum of the system is given by:
p2 = (m1 + m2) x v2
where m2 is the mass of the firecracker and v2 is the velocity of the can after the explosion.
By equating the initial and final momenta and solving for v2, we get:
v2 = 0 m/s.
So, the speed of the can after the explosion is 0.83 m/s

5. A 4.0 kg model rocket is launched, shooting 50.0 g of burned fuel from its exhaust at an average velocity of 625 m/s. What is the velocity of the rocket after the fuel has burned?
Answer:
To find the velocity of the rocket after the fuel has burned, we need to use the conservation of momentum principle. The principle states that the momentum of an isolated system (in this case, the rocket and the expelled fuel) is constant, meaning that the initial momentum of the system is equal to the final momentum of the system.
The initial momentum of the system is the momentum of the rocket before the fuel is expelled, which is given by:
p_initial = m_rocket * v_initial = 4.0 kg * 0 m/s = 0 kg m/s
The final momentum of the system is the momentum of the rocket after the fuel is expelled, which is given by:
p_final = m_rocket * v_final
The momentum of the expelled fuel is given by:
p_fuel = m_fuel * v_exhaust = 0.05 kg * 625 m/s = 31.25 kg m/s
The total momentum of the final system is the sum of the rocket and the expelled fuel.
p_total = p_rocket + p_fuel
Now we can use conservation of momentum equation
p_initial = p_final
0 = m_rocket * v_final + m_fuel * v_exhaust
Now we can solve for v_final
v_final = (p_initial - p_fuel) / m_rocket
v_final = (0 - 31.25 kg m/s) / 4.0 kg = -7.8125 m/s
So the final velocity of the rocket after the fuel is expelled is -7.8125 m/s, which means that the rocket is moving in the opposite direction of the expelled fuel.
how can you be able to tell if a force is acting on an object by looking at the velocity time graph?
If the velocity is changing over time, then you know there's an external force being acted on the object. You can tell this by Newton's Second Law F=MA where acceleration is change of velocity over change in time. As a result, if the velocity starts to change, then you know an external force is present on the object.

an electric motor rotating a grinding wheel at 96 rev/min is switched off. (a) with constant negative angular acceleration of magnitude 2.02 rad/s2, how long does it take the wheel to stop?
The time that take the wheel to stop is: 1.04 s.
To calculate the time it takes for the wheel to stop, we can use the equation t = ω/α, where ω is the initial angular speed (in radians/second) and α is the angular acceleration.
Since the wheel's initial angular speed is 96 rev/min, we can convert this to radians/second by multiplying by 2π/60, which gives us 2.094 rad/s. Therefore, the time it takes for the wheel to stop with a constant negative angular acceleration of magnitude 2.02 rad/s2 is given by t = 2.094/2.02 = 1.04 s.

what magnitude of acceleration does it need to have to come to a complete stop in a distance of 200 ft ?
The magnitude of acceleration required to come to a complete stop in a distance of 200 ft depends on the initial velocity of the object.
What is acceleration?
Acceleration is the rate of change of an object's velocity. It is usually measured in meters per second squared (m/s2) and is often denoted by the letter "a". Acceleration can be caused by a variety of factors, including a change in speed, direction, or both. It is often associated with gravity, as objects naturally accelerate towards the ground due to the force of gravity. However, acceleration can be caused by any external force, such as a rocket engine, a car engine, or a person pushing an object. Acceleration is used in many aspects of physics, such as calculating the motion of an object, the force of a collision, and the acceleration of an object due to gravity. It is also used to calculate the amount of energy required to launch a rocket into space. Acceleration can be used to describe the speed at which an object is moving, as well as the rate at which it is changing direction.

If a beam of radiation containing 1000 x-rays is spread out over a square field that measures 10 inches long and 10 inches wide, what is the concentration of x-rays per square inch?
a. 1 x-ray/in squared
b. 10 x-rays/in squared
c. 100 x-rays/in squared
d. 1000 x-rays/in squared
e. 10,000 x-rays/in squared
The concentration of x-rays in a given area can be calculated by dividing the total number of x-rays by the area. In this answer, we will determine the concentration of x-rays per square inch in a beam of radiation containing 1000 x-rays spread out over a square field that measures 10 inches long and 10 inches wide.
First, we need to calculate the total area of the square field. To do this, we multiply the length by the width, which gives us 10 inches * 10 inches = 100 square inches. Next, we divide the total number of x-rays by the total area to find the concentration of x-rays per square inch. In this case, 1000 x-rays / 100 square inches = 10 x-rays per square inch.
So, the answer is (c) 100 x-rays per square inch. It is important to note that the concentration of x-rays in a given area will vary based on the number of x-rays and the size of the area being considered. The above calculation assumes a uniform distribution of x-rays, but in real-world scenarios, the distribution may not be uniform and the concentration of x-rays may vary based on factors such as the angle of the beam, the distance from the source, and the presence of any obstructions.

what would happen if you used very large amplitudes? check your hypothesis by trial. what amplitude did you use? what is the result?
The amplitude of a wave is proportional to the amount of energy it carries. When the amplitude of a wave is increased, the energy carried by the wave also increases. This can result in several potential outcomes, depending on the specific wave system being considered.
In mechanical wave systems, such as a vibrating string or a loudspeaker, using very large amplitude can cause the system to become nonlinear, meaning that the wave behavior deviates from the expected linear relationship between the wave amplitude and energy. Nonlinearities can cause the wave to generate harmonics, which are higher frequency components in the wave spectrum. They can also cause the wave to become distorted, producing a sound that is different from the original waveform. In extreme cases, the system can become mechanically unstable and break or stop functioning altogether.
In electromagnetic wave systems, such as radio waves or light waves, very large amplitudes can cause similar nonlinear distortions. They can also cause unwanted interference with other signals in the system, as well as increase the risk of damage to the transmitting or receiving equipment.
It is important to use appropriate amplitudes for the specific wave system being considered, as excessive amplitudes can result in unwanted side effects and potentially cause damage to the system.

a ball is tossed vertically upward with an initial speed of 21.9 m/s. how long does it take before the ball is back on the ground?
The ball will take approximately 4.46 seconds to return to the ground.
T = 2v/g, where v is the starting velocity and g is the acceleration due to gravity (9.8 m/s2), can be used to calculate the time it takes for a ball to fall to the earth after being thrown vertically upward with an initial speed of 21.9 m/s.
The time it takes the ball to reach its highest point must first be determined. This can be found by rearranging the equation: t = v/g, which gives us: t = 21.9/9.8, or 2.24 seconds.
Next, we must determine how long it takes for the ball to fall to the ground. To calculate this, we must multiply the time it takes the ball to fall back to the ground by the time it takes it to reach its highest point (2.24 seconds).
Since the ball has the same initial speed as when it was thrown upward (21.9 m/s), we can use the same equation to calculate this time: t = 2v/g, which gives us: t = 2(21.9)/9.8, or 4.46 seconds.

A piece of aluminum foil measures 8.65 cm by 8.31 cm and has a mass 0.313 g. the density of aluminum is 2.70 g/cm3. The thickness of the aluminum foil is 0.0016 cm.
Given,
The length (l) and breadth (b) of aluminum foil is 8.65cm and 8.31 cm. And let the thickness of the foil be 'x'.
The mass (m) of the foil is 0.313 g.
The density (D) of the aluminum is 2.70 g/cm³.
