Question

A cricket ball of mass 100g moving with a speed of 30 m/s is brought to rest by a player then find the change in momentum of ball

Answer 1

Answer:

mass of ball =100g=0.1kg

initial velocity =30m/s (u)

final velocity=0m/s (v)

Change in momentum= Final momentum-initial momentum

=mv-mu

=m(v-u)

=100(0-30)

=100×-30

= -3000

negative sign indicates that the force applied by the player on the ball acts in opposite direction
