A blue ball is thrown upward with an initial speed of 24.3 m/s, from a height of 1 meters above the ground. 3 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 10.9 m/s from a height of 32.3 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.

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