A ball is moved on a horizontal table with some velocity. The ball stops after moving some distance. Which external force is responsible for the change in the momentum of the ball?

Consider the situation of the previous problem. Take the table and the ball is then an intenal force. As the ball slows down the momentum of the system decreases. Which external force is responsible for this change in the momentum?

Gregory rolls a plastic ball on the floor. The ball stops after rolling a certain distance. The ball stops because of the presence of

A ball moving with a velocity v strikes a wall moving toward the wall with a velocity u. An elastic impact occurs. Determine the velocity of the ball after the impact. What is the cause of the change in the kinetic energy of the ball ? Consider the mass of the wall to be infinitely great.

What is done to stop a moving ball?

A ball is projected horizontal from the top of a tower with a velocity v_(0) . It will be moving at an angle of 60^(@) with the horizontal after time.

A truck is moving horizontally with velocity v. A ball thrown vertically upward with a velocity u at angle theta to the horizontal from the truck relative to it. The horizontal range of the ball relative to the ground is

The moving ball on the floor stops after some time because of………

A ball of mass 'm' moves normal to a wall with a velocity 'u' and rebounde with the same speed. The change in momentum of the ball during the rebounding is
