Answer :
Answer:
The kinetic energy is transferred from the ball to the bumper. The bumper gives the same energy back and the ball eventually stopped due to friction of the ground.
Explanation:
Hope this y'all <3
When the ball hits/bounces off the bumper kinetic energy is transferred between the bumper and the ball, while the slowing down is caused by surface friction ( applied force )
In the scenerio explained in the question there is an applied force between the surface and the pool ball, and an energy transfer occurring between the pool ball and the bumper.
- When the pool ball hits the bumper; Kinetic energy is transferred from the pool ball to the bumper
- When the pool ball bounces off the bumper: The Kinetic energy absorbed by the bumper is transferred from the bumper back pool ball.
- When the ball comes to a halt : The applied force ( frictional force ) between the ball and the surface causes the ball to come to a halt.
hence the applied force that cause the ball to come to a halt is friction while the energy transferred is Kinetic energy ( between the ball and bumper )
