A blue ball is thrown upward with an initial speed of 23.9 m/s, from a height of 0.5 meters above the ground. 2.9 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 7.5 m/s from a height of 31.5 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/s^2.

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