Problem
A force of 50N acts on a ball of mass 2.0kg moving initially with a velocity of 5ms−1 in the same direction as the force for 4s. Answer the following:
(i) Find the initial momentum of the ball.
(ii) Calculate the change in momentum produced by the force.
(iii) Determine the final velocity of the ball at the end of 4s.
