A tennis ball is struck such that it leaves the racket horizontally with a speed of 53 m/s. The ball clears the net and hits the ground a horizontal distance 29 m from where it was hit. How long was the ball in the air and how high was the ball above the ground when it is hit?
Now, knowing time in air,how far does a ball fall in that time?
distance=1/2 g time^2
