In the "before" part of the figure, car A (mass 1200 kg) is stopped at a traffic light when it is rear-ended by car B (mass 1300 kg). Both cars then slide with locked wheels until the frictional force from the slick road (with a low μk of 0.20) stops them, at distances dд = 7.9 m and dB = 6.2 m. What are the speeds of (a) car A and (b) car B at the start of the sliding, just after the collision? (c) Assuming that linear momentum is conserved during the collision, find the speed of car B just before the collision. Before After
