Question

A hockey ball of mass 200 g travelling at
10 m s-7 is struck by a hockey stick so as
to return it along its original path with a
velocity at 5 m s-?. Calculate the change
of momentum occurred in the motion of
the hockey ball by the force applied by
the hockey stick.

Answer 1

Explanation:

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.

Answer 2

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.
