A car and a truck collide on a very slippery highway. The car, with a mass of 1600 kg, was initially moving at 50 mph. The truck, with a mass of 3000 kg, hit the car from behind at 65 mph. Assume the two vehicles form an isolated system in what follows. (a) If, immediately after the collision, the vehicles separate and the truck's velocity is found to be 55 mph in the same direction it was going, how fast (in miles per hour) is the car moving? (b) If instead the vehicles end up stuck together, what will be their common velocity immediately after the collision? In particular, answer the following questions: (a) What is the coefficient of restitution for the collision described in part (a) of the problem, and how auch kinetic energy is "lost" in that collision? (b) What is the coefficient of restitution for the collision described in part (b) of the problem, and how much kinetic energy is "lost" in that collision?
