4. a golfer practicing on a range with an elevated tee 4.5 m above the fairway is able to strike a ball so that it leaves the club with a horizontal velocity of 20m/s. (assume the acceleration due to gravity is 9.8 m/s² and the effects of air resistance may be ignored unless otherwise stated.
a) how long after the ball leaves the club will it land on the fairway?
b) what horizontal distance will the ball travel before striking the fairway?
c) what is the acceleration of the ball 0.5 s after being hit?
d) calculate the speed of the ball 0.8 s after it leaves the club
e) with what speed will the ball strike the ground?
