A blue ball is thrown upward with an initial speed of 24.1 m/s, from a height of 0.6 meters above the ground. 2.9 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 8.5 m/s from a height of 31.8 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.
What is the speed of the blue ball when it reaches its maximum height
