a hockey ball of mass 200g travelling at 10ms-1is stuck by a hockey stick so as to return it along it's original pat with a velocity at 5ms-1.calculate the change of momentum occurred in the motion of a hockey ball by the force applied by the hockey stick

Expert Answer:

Initial velocity = 10 m/s, final velocity = -5 m/s (Becuase it's in the opposite direction).
Change in momentum = Final Momentum - Initial Momentum
 = Mass(Final Velocity - Initial Velocity)
= (200/1000) (-5-10) = -3 kg.m/s
