In a game of cricket, a ball leaves a bat in a horizontal direction from a height of 0.39 m above the ground.
The speed of the ball is 35 m s–1.
(a) Calculate the time interval between the ball leaving the bat and reaching the ground. [3]
(b) What horizontal distance does the ball travel in this time? [2]
(c) Fielders are not allowed within 15 m of the bat.
What is the maximum speed that the ball should leave the bat, travelling in a horizontal direction, for the player not to be caught out? [2]
