As a tennis ball is struck, it departs from the racket
horizontally with a speed of 29.0 m/s. The ball hits the court at a
horizontal distance of 20.3 m from the racket. How far above the
court is the tennis ball when it leaves the racket?
m
Time taken by the ball to reach the court t = R/u
t = 20.3/29 =0.7 sec
height of the rocket from court h = gt2/2
h = 10*0.49/2 =2.45 m
