Question

A hockey player hits a ball of 0.1 kg mass lying on the ground at rest with his stick.It is found that the ball starts moving with Final velocity of 40 m/sec.Initial velocity u=0m/sec. Find impulse of the force inserted on the ball​

Answer 1

Impulse = change in momentum = (final momentum - initial momentum) = m(final velocity- initial velocity)

= 0.1(40-0) = 4Ns
