A charging bull elephant with a mass of 5240 kilogram comes directly towards you with a speed of 4.55 m/s. You toss a rubber ball at the elephant with a speed of 7.81 m/s.
a.) When the ball bounces back toward you, evaluate what is its speed?
b.) Find how do you account for the fact that the ball's kinetic energy has increased?
