Decide the initial speed of the second ball

Reference no: EM13673268

A ball (first ball) is dropped from rest from a height 20.0 m above the ground. Another ball is thrown (second ball) vertically upward from the ground at the instant the first ball is released. Decide the initial speed of the second ball if the two balls are to meet at a height 10.0m above the ground.
