A red ball is thrown down with an initial speed of 1.2 m/s from a height of 26 meters above the ground. Then, 0.4 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.8 m/s, from a height of 1 meter 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. a. What is the height of the blue ball 1.8 seconds after the red ball is thrown?
b. How long after the red ball is thrown are the two balls in the air at the same height?
