Question

a cricket ball of mass 100 gram moving at a speed of 30 ms^1 is brought to rest by player in 0.03 seconds find the average force applied by the player

Answer 1

Mass of ball=100gm =.1kg
u=30m/s^1
v=0m/s^1
t=.03 s

Force= mass× acceleration
Acceleration=v-u÷t
0-30÷.03
=-30÷.03

F=.1×-30÷.03
F=-100N
