To Explain: Whether a force is needed for the bounce of the basketball.
The agent of force that is involved in the bouncing of the ball.

Answer to Problem 46A
Yes, a force is needed for the bounce of the basketball.
The floor acts as an agent of force that is involved in the bouncing of the ball.
Explanation of Solution
Consider a basketball player drops a ball on the floor. The ball moves downward with a particular velocity in the downward direction.
When the ball hits the floor, it bounces up with different velocity in the upward direction.
Hence, the direction of the velocity of the ball is changed resulting in the acquisition of certain acceleration by the ball.
The ball requires a force in order to attain this acceleration of the ball.
Thus, a force is needed for the bounce of the ball.
The ball bounces after hitting the hard surface of the floor.
Hence, the floor acts as an agent of force involved in the bouncing of the ball.
Conclusion:
Thus, a force is involved in the bouncing of the ball and the floor acts as an agent of force involved in the bouncing of the ball.

Sheararrow_forwardA bungee jumper plans to bungee jump from a bridge 64.0 m above the ground. He plans to use a uniform elastic cord, tied to a harness around his body, to stop his fall at a point 6.00 m above the water. Model his body as a particle and the cord as having negligible mass and obeying Hooke's law. In a preliminary test he finds that when hanging at rest from a 5.00 m length of the cord, his body weight stretches it by 1.55 m. He will drop from rest at the point where the top end of a longer section of the cord is attached to the bridge.
