A blue ball is thrown upward with an initial speed of 24.3 m/s,from a height of 0.9 meters above the ground. 3 seconds after theblue ball is thrown, a red ball is thrown down with an initialspeed of 8.2 m/s from a height of 33.3 meters above the ground. Theforce of gravity due to the earth results in the balls each havinga constant downward acceleration of 9.81 m/s2.
4) What is the height of the red ball 3.9 seconds after the blueball is thrown?
5) How long after the blue ball is thrown are the two balls inthe air at the same height?
