Question

- A hockey ball of mass 200 g travelling at 10 ms' is struck by
a hockey stick so as to return it along its original path with a
velocity at 5 msl. 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

Answer:

A hockey ball of mass 200 g travelling at 10 m s-1 is struck by a hockey stick so as to return it along its original path with a velocity at 5 m s-1. ... Hence, the change in momentum of the hockey ball is 3 kg m sˆ'1.
