Physical Sciences November 2016 Paper 1 Question 4 Momentum and Impulse "The graph below shows how the momentum of car A changes with time just before and just after a head-on collision with car B. Car A has a mass of 1 500 kg, while the mass of car B is 900 kg. Car B was travelling at a constant velocity of 15 m∙s-1 west before the collision. Take east as positive and consider the system as isolated"
