Two perfectly elastic balls, the larger of mass M and the smaller of mass m, with m << M, are dropped from a height h >> radius of either ball above a solid surface. Mass M rebounds elastically from the surface and mass m rebounds elastically from M. Find the height H that the small ball reaches in terms of h.
Ball loses 25% of (final K.E.), so initial energy with which it bounces back = 75% of (final K.E) = (3/4) × 120M = 90M. So to find the height to which the ball will bounce back we equate the initial energy (that is 90M) with the final energy (that is potential energy at the maximum height to which the ball has bounced). 90M = MgH H= 9 metres.

Since the velocity of the ball is $0 \frac{ft}{s}$ when the ball is at its maximum height of $132ft$, you can calculate it starting from there. Since this is more of a physics problem than a math problem, I'm going to do this the more Physics-y way. To make it easier, I'm converting this to meters. $132ft = 40.2336m \approx 40m$. Elastic collisions occur when the collision force is a non-contact force. Most collisions are not inelastic because the collision forces cause energy of motion to be transformed into sound, light and thermal energy (to name a few).
