Chapter 07, Problem X11 An automobile has a mass of 1760 kg and a velocity of 20.2 m/s. It makes a rear-end collision with a stationary car whose mass is 2100 kg. The cars lock bumpers and skid off together with the wheels locked. (a) What is the velocity of the two cars just after the collision? (b) Find the impulse that acts on the skidding cars from just after the collision until they come to a halt. (c) If...

5. A runaway truck with a mass of 2100 kg strikes a car of mass 1350 kg, which was at rest before the collision. The car’s wheels are locked during the entire event, but the truck has no brakes, i.e., it is rolling freely on the road. The two vehicles move forward together, and the car’s tires leave skid marks for a distance of 1.5 m. Suppose that the coefficient of kinetic friction between the car’s tires and the road...
