# A rubber ball bounces off of a wall with an initial speed \(v\) and reverses its direction so its speed is \(v\) right after the bounce. As a result of this bounce, which of the following quantities of the ball are conserved?

A rubber ball bounces off of a wall with an initial speed \(v\) and reverses its direction so its speed is \(v\) right after the bounce. As a result of this bounce, which of the following quantities of the ball are conserved?

- **A.** just the momentum of the ball
- **B.** just the kinetic energy of the ball
- **C.** both the momentum and the kinetic energy of the ball
- **D.** None of the above quantities are conserved.
