A block of mass =1.25 kg slides along a horizontal table with speed 0=8.00 m/s. At =0, it hits a spring with spring constant =80.00 N/m, and it also begins to experience a friction force.

The coefficient of friction is given by =0.100. How far has the spring compressed by the time the block first momentarily comes to rest?

Answers

Answer 1

The distance travelled by the spring compressed by the time the block first momentarily comes to rest is equal to 0.96 meters.

what is work energy theorem?

work energy theorem is an important phenomenon in physics which states that the change in kinetic energy is equal to the work done by the object.

This law is basic part of conservation of energy.

what is newtons law of motion?

Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it. These laws can be paraphrased as follows: A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force.

given:

mass of the block = 1.25 kg

speed of the block = 8.0 m/s

spring constant = 80 N/m

coefficient of friction = 0.100 u

on applying the work energy theorem, you would realize,

change in kinetic energy = work done by spring and the friction

final kinetic energy - initial kinetic energy = work done by spring + the work done by friction

0.5 × 1.25 × 64 = 0.5 × 80 × x² + 0.1 × 1.25 × 9.8

x = 0.96 meters

therefore, the distance travelled by the spring compressed by the time the block first momentarily comes to rest is equal to 0.96 meters.

What is the average speed of a particle in the
medium during one cycle?

Answers

A wave period 10ms travels through a medium. The graph shows the variation of particle displacement with distance for the wave. The average speed of a particle in the medium during one cycle is (v)= 20 m/s.

What is velocity?

The velocity is a physics term that means a matter that covers a distance in a particular time. its a vector quantity. It can be measured in m/s or cm/s.

How can we calculate the velocity of the wave?

To calculate the average velocity we are using the formula is,

v=d/t

Here we are given,

According to the picture the wave start from +4.0 displacement and goes decreasing at -4.0 and then comes back at +4.0 and completes the full cycle and complete the amount of distance is (d)= 20cm = 0.2m

The period of the wave is (t)= 10ms = 10*10⁻³ s

We have to calculate the  average speed of a particle in the medium during one cycle= v m/s.

Now we put the values in the above equation we get,

v=d/t

Or, v= 0.2/ 10*10⁻³

Or, v= 20 m/s

So from the calculation we can say that, The average speed of a particle in the medium during one cycle is (v)=20 m/s.

You are interested in retrieving a souvenir from a shipwreck located 115 feet below the water. The path of your dive is modeled by the equation y = 0.05x2 - 4x - 38. Assuming you can hold your breath for the duration of the dive, will you be able to retrieve your souvenir? why?

Answers

In order to find out if we will be able to retrieve the souvenir, let's use y = -115 (negative because it's below the water) in the equation and calculate the value of x.

If there is at least one real solution, we will be able to retrieve the souvenir.

To solve this quadratic equation, let's use the quadratic formula:

[tex]\begin{gathered} y=0.05x^2-4x-38 \\ -115=0.05x^2-4x-38 \\ 0.05x^2-4x-38+115=0 \\ 0.05x^2-4x+77=0 \\ a=0.05,b=-4,c=77 \\ x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a} \\ x_1=\frac{-(-4)+\sqrt[]{(-4)^2-4\cdot0.05\cdot77}_{}}{2\cdot0.05} \\ x_1=\frac{4+\sqrt[]{16-15.4}_{}}{0.1} \\ x_1=\frac{4+0.77}{0.1}=47.7 \\ x_2=\frac{4-0.77}{0.1}=32.3 \end{gathered}[/tex]

The acceleration of an object is equal to the net force acting on the object divided by its mass. A change in the velocity of an object is an increase or decrease in velocity or a change in direction of motion. Examples of acceleration include falling apples, orbiting the moon, and stopping a car at a traffic light.

Rocket acceleration is based on an applied force known as thrust, an example of Newton's second law of motion. Another example of Newton's second law is that when an object falls from a certain height, it accelerates due to gravity. An initial positive acceleration corresponds to a change in velocity away from zero in the first step. A constant walking motion then produces an acceleration that oscillates from positive to negative averaging to zero.

Answers

The cyclist has moved 115.5 meters from the check point to the point of turning back.

As, we can see, the acceleration is constant,

We can use equation of motion,

S = ut + 1/2at²

Where s is the displacement,

u is the initial velocity,

t is the time taken,

a is the acceleration,

In the question it is given,

Initial velocity is 5.5m/s,

Acceleration is 0.55m/s²,

Time taken is 20 seconds,

Here, S is the distance between the cyclist's check point and the returning point,

Putting all the values,

S = 5.5x20 + 1/2x0.55x20

S = 110 + 5.5

S = 115.5 meters.

Hence, the distance between the check point and returning point is 115.5 meters.

What is the difference between the conservation of mechanical energy and the no conservation of mechanical energy?

Answers

Conservation of mechanical energy only holds in a frictionless environment where all collisions are perfectly elastic. It shows that the sum of the kinetic and potential energies of an isolated system becomes a time-independent constant.

Energy conservation states that the sum of all energies not only kinetic and potential but also heat chemical energy etc. in an isolated system is constant. The former is a special case of the latter, and the latter is a universal law, but it is often inapplicable because it must account for all of the observable universes.

According to the law of conservation of mechanical energy the total mechanical energy of the system is conserved. That is, energy is neither created nor destroyed. The internal transformation from one form to another is possible only if the forces acting on the system are of a conservative nature. Mechanical energy is not conserved unless non-conservative forces are acting as friction and other dissipative forces directly convert work or ME into thermal energy.

Select the correct answer. When a substance changes from one phase to another, which of the following events occurs? A. The substance loses or gains heat. B. The average kinetic energy of the substance changes. C. The temperature of the substance changes. D. The molecular motion of the substance changes.

Answers

When a substance changes from one phase to another, which of the following events occurs (A) The substances loses or gains heat.

A Phase change is reversible physical change that happens when a substance changes from one state of matter to the another state of matter. when substances changes from solid , liquid or gas state to different state called as phase change. Temperature can change the substance from one phase to another. for example . we can freeze the water by putting it to freezer to change it into ice and when we put it on heat it changes to liquid.

Thus, When a substance changes from one phase to another, which of the following events occurs (A) The substances loses or gains heat.
