A rubber ball is shot straight up from the ground with speed Vo.Simultaneously, a second rubber ball at height,h, directly abovethe first ball is dropped from rest.
a. At what height above the ground do the balls collide?
b. what is the max value of h for which a collision occursbefore the first ball falls back to the ground?
c. for what value of h does the collision occur at the instantwhen the first ball is at its highest point?
