A charging bull elephant with a mass

Reference no: EM13653308

A charging bull elephant with a mass of 5240 kg comes directlytoward you with a speed of 4.55m/s. You toss a 0.150 kg rubber ballat 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 balls kinetic energy has increased?
