Question

A hockey ball of mass 200g travelling at 10m/s square is struck by a hockey stick so as to return it along its original path with a velocity at 5m/s square Calculate the magnitude of change of momentum occurred in the motion of the hockey ball by the force applied by the hockey stick

Answer 1

This is the solution :_

Answer 2

Answer:

Explanation:

Let the initial momentm = mu=0.2×10= 2kg m/s

And final momentem= mu= 0.2×(-5)= 1 kg m/s

Because change in momentem= m(v-u)

=(-1-2)

=-3kg m/s
