Q1. 3/204 from the book, slightly extended/modified. Freight car A of mass ma is rolling to the right with speed vo when it collides with freight car B of mass mg initially at rest. The two cars are coupled together at impact, so that they move together with a common velocity ("plastic collision"). Answer all the questions below in terms of quantities given, namely, v, ma and mB. a) Compute their common velocity immediately after the impact b) Compute the impulse of car A on car B. Note: Impulse on car B = Momentum change of car B. c) Compute the loss in total kinetic energy of the system (A+B) due to the collision. A
