A blue ball is thrown upward with an initial speed of 21.2 m/s, from a height of 0.5 meters above the ground. 2.6 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 11.7 m/s from a height of 25.7 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2.

A) What is the speed of the blue ball when it reaches its maximum height?

B) What is the height of the red ball 3.38 seconds after the blue ball is thrown?

C) How long after the blue ball is thrown are the two balls in the air at the same height?
