a rubber ball is shot straight up from the ground with speed v0. simultaneously, a second rubber ball at height h directly above the first ball is dropped from rest.
part a. at what height above the ground do the balls collide? your answer will be a symbolic expression in terms of v0, h, and g .
part b.
what is the maximum value of h for which a collision occurs before the first ball falls back to the ground?
express your answer in terms of the variable v0 and appropriate constants.
part c.
for what value of h does the collision occur at the instant when the first ball is at its highest point?
express your answer in terms of the variable v0 and appropriate constants.
note: can you work the problem out and not just give me the equations for each.
