ABSTRACT
Problem 1. Determine the momentum of a pile driver of mass 400 kg when it is moving downwards with a speed of 12m/s.
Momentum D massð velocity D 400 kgð 12m/s D 4800 kgm=s downwards
Problem 2. A cricket ball of mass 150 g has a momentum of 4.5 kgm/s. Determine the velocity of the ball in km/h.
