A cricket ball of mass 100 g moving with a speed of 40 m/s is brought to rest by a player in 0.02s. Find the average force applied by the player.
15 N
200 N
5 N
6 N
Force applied = Mass*(rate of change in momentum with time)
Force = 0.1x400.02 = 200 N
A cricket ball of mass 200 g moving with a speed of 40 ms−1 is brought to rest by a player in 0.04s. Calculate the following : (i) change in momentum of the ball, (ii) average force applied by the player. [2 MARKS]
