Suppose Ball 1 is at a height of 19.6 m when it reaches the top of its trajectory. At the instant Ball 1 is at the top of its trajectory, Ball 2 is released from rest at the same height. How much time does it take for either ball to reach the ground? Note that the vertical component y of the ball’s displacement points downward, in the -y direction.
