A ball of mass 100g moving with velocity 10m s

Asked by admin @ 06/08/2021 in Science viewed by 304 People

A ball of mass 100g is moving with a velocity 10m/s is stopped by a boy in 0.2 seconds. Calculate the force applied by the boy to stop the ball.

Answered by admin @ 06/08/2021

Mass of ball =100g , velocity of ball= 10m/s ,ball stop by boy in 0.2 sec.then force=mass×acceleration but acceleration is not given,acceleration=initial velocity - final velocity/time ,but initial velocity= 10m/s and final velocity=0m/s and time = 0.2 second. therefore,acceleration =10-0/0.2=50,therefore,force=m×a=100×50=500 Newton
