A charging bull elephant with a mass of 5240 kg comes directly toward you with a speed

Question:

A charging bull elephant with a mass of 5240 kg comes directly toward you with a speed of 4.55 m/s. You toss a 0.150-kg rubber ball at the elephant with a speed of 7.81 m/s.

(a) When the ball bounces back toward you, what is its speed?

(b) How do you account for the fact that the ball's kinetic energy has increased?
