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 \(5\ m\ s^{–1}\). Calculate the magnitude of change of momentum occurred in the motion of the hockey ball by the force applied by the hockey stick.
Let us consider,
\(m\) be the mass of the object
\(u\) be the initial velocity of the ball
\(v\) be the final velocity of the ball
We know that the formula to calculate the initial momentum of the ball,
We know that the formula to calculate the final momentum of the ball,
We know that the formula to calculate the change in momentum,
Change in momentum \(=\) \(kg\ m\ s^{-1}\)
(Note: Enter your answer with no decimal places)
