Question

A hockey ball of mass 200g traveling from west to east at 10m/s is struck by a hockey stick. As a result, then ball gets turned back and now has a speed of 5m/s. If the ball and hockey stick were in contact for 0.2 s, calculate (i) initial and final momentum of the ball (ii) rate of change of momentum of the ball (iii) the force exerted by hockey stick on the ball class 9.

Answer 1

Answer:

Calculate the change of momentum occurred in the motion of the hockey ball by the force applied by the hockey stick. Hence, the change in momentum of the hockey ball is 3 kg m sˆ'1.
