Question

A hockey ball of mass 200 g travelling at 10-m s' is struck by
a hockey stick so as to return it along its original path with a
velocity at 5 m s-1. Calculate the change of momentum occurred
in the motion of the hockey ball by the force applied by the
hockey stick.​

Answer 1

Explanation:

solution is attached herewith

Answer 2

$change \: in \: momentum = m(vf - vi)$

$change \: in \: momentum = \frac{200}{1000} (5 - 10)$

$change \: in \: momentum = \frac{2}{10} \times ( - 5)$

$change \: in \: momentum = - 1$
