Every action has an equal and opposite response, according to Newton's Third Law.
Explain about the Newton's 3rd law relate to a rocket?Newton's Third Law of Motion is essential for rocket launch. Through action and reaction, a rocket engine generates thrust. Hot exhaust gases from the engine exit via the back of the engine. In response, the opposing reaction produces a propelling force.
Forces always act in pairs that are equal but opposite, according to Newton's third law of motion. Another way to put it is that there is an equal but opposing reaction to every action. In other words, when you push against a wall, the wall pushes back at you with a force equal to your own.
There is an equal and opposite reaction to every action, according to Newton's third law. The implication of the statement is that there are always two forces acting on the two interacting objects. The force acting on the first object is equal in size to the force acting on the second.

A) 9.04o B) 4.55o C) 3.14o D) ) 0.08o E) none of the above
Option A is correct.
9.04 degree is the angle that the total acceleration of the car makes with the radius of the circle.
What is speed?Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.
What is acceleration?Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
How to calculate angle when the car completes first half of the circle?When car completes half of the circle it means distance covered would be half the perimeter of the circle.
s = ut + 1/2at²
2πr/2 = 0 + 1/2at²
a(tangential) = 2πr/t²............(1)
where s = distance
u = initial velocity
a = acceleration
t = time
We know that centripetal force is :
a(centripetal) = v²/r ............ (2)
Now we using first equation of kinematics,
v = u +at
Put the values from equation(1):
We get,
v = 0 + 2πr/t² × t
where v = final velocity
u = initial velocity
a = acceleration
t = time
Now the put the obtained value in equation(2)
a = 4π²r/t²
To get the angle we can use this expression :
θ = tan⁻¹ [ a(T)/a(C) ]

A 120 kg hoop rolls along a horizontal floor so that the hoop's center of mass has a speed of 0.180 m/s. How much work must be done on the hoop to stop it?
___ J
The work that must be done on the hoop to stop it is calculated to be -3.888 J.
As the mass of the hoop is 120 kg and the hoop's center of mass has a speed of 0.180 m/s, the rotational inertia can be given as follows;
I= mr^2
I=120r^2
The kinetic energy of hoop = Linear kinetic energy + Rotational kinetic energy
K= (1/2mv^2) + (1/2Iw^2)
But; w= (v/r)^2
K= (1/2mv^2) + (1/2×120r^2(v/r)^2)
K = (1/2×120×0.180^2) + (1/2×120×0.180^2)
K = 3.888 J
To stop the hoop, its final kinetic energy must be 0, therefore;
Work done = Kfinal-Kinitial = 0 - 3.888
W= -3.888 J
Hence, -3.888 J of work must be done to stop the hoop.

What is initial velocity?
A physical system's behaviour in terms of the its motion is described using equations of motion. The equations are relationships between different terms and quantities. There are primarily three equations of motion, also known as the laws of constant acceleration, that apply when there is uniform acceleration. Any object subject to forces will accelerate. The object's velocity changes as a result of this acceleration. As a result, the initial velocity is indeed the object's speed before the change brought on by acceleration. The velocity will become the final velocity after the object has been accelerating for a while.
Her speed at the bottom of the arc would depend on the magnitude of the initial velocity and the angle she is swinging out to.
Assuming that the initial velocity is constant, the speed at the bottom of the arc can be calculated using the equation:
v = v0 * cos(θ)
where v0 is the initial velocity and θ is the swing angle.
In this case, v0 is the initial velocity and θ is 45°, so the speed at the bottom of the arc would be:

If you hang a shape from one point you'll find that the center of mass is always directly below that point. So if you hang a shape from two different points and draw a line down from each point the center of mass is where those lines intersect.
The product of the total mass of the system and the position vector of the center of mass equals the sum of the products of the masses of the two particles and their respective position vectors. The center of mass is a position defined relative to an object or system of objects.

What evidence have you discovered to explain how kinetic energy and mass are related
Explanation:
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
behavior therapists look to current environmental events that maintain problem behaviors and help clients produce behavior change by changing environmental contingencies (T/F).

Through the process of functional assessment, behavior therapists look to the current environmental events that maintain problem behaviors and help clients produce behavior change by changing environmental events.
Functional assessment is used to determine an individual's level of functioning and his or her ability to perform specified tasks on a safe and predefined environment over a defined period. An FBA is the process of determining the reasons (or “functions”) of behavior before producing an intervention, which is based upon hypothesized causes (functions) of behavior and understanding why a behavior occurs facilitates a more targeted and effective intervention.There are components of functional assessment, which includes- Vision and hearing, mobility, continence, nutrition, mental status, affect, home environment, social support, activities of day to day life such as transferring, ambulating, bathing, etc.Hence, through the process of functional assessment, behavior therapists look to the current environmental events that maintain problem behaviors and help clients produce behavior change by changing environmental events.

A 22.4 kg block is placed on a ramp that makes an angle of 22 ° to the horizontal. The coefficient of friction between the block and the ramp is 0.11. The block is released from rest and allowed to slide down the ramp. What is the acceleration of the block?
Answer: 2.67 m/s2
Explanation:
W = mg = (22.4 kg)(9.8 m/s2) = 219.52 N
Wx = (219.52 N)(sin 22) = 82.2 N
Wy = (219.52 N) (cos 22) = 203.5 N
Wy = N (normal force on the block) = 203.5 N
Ff (force of friction) = (coeff. friction)(N) = (0.11)(203.5 N) = 22.4 N
Sum the forces in the x-direction (direction of motion down the ramp):
Fnet = Wx - Ff = 82.2 N - 22.4 N = 59.8 N
a = F/m = 59.8 N / 22.4 kg = 2.7 m/s2

Describe mass.In physics, mass is a quantification of inertia, a basic characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the use of a force. The change caused by a force applied is smaller the more mass a body has.
Describe the mass formula.The mass with one mole of a chemical substance or the ratio of a mass of a chemical to its number of chemicals substance is known as the molar mass (M), which is a physical attribute.
