Question

A cricket ball of mass 100 g moving at a speed of 30 m/s is brought to rest by a player in 0.03 s. find the average force applied by the player.

Answer 1

mass = 0.1kg.

Explanation:

initial management = M * speed (u) = 0.1 *30 = 3

Final momentum =m*rest (v) =0.1*0=0

change in momentum =final -initial =0-3=-3

Rate of change in momentum /time taken =(-3)/00.03=100
