Ablue ball is thrown upward with an initial speed of 21.8 m/s, from a height of 0.9 meters above the ground. 2.7 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 10.4 m/s from a height of 26.6 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.
