Bonus : In the "before" part of the shown Figure, car A (mass 1100 kg) is stopped at a traffic light when it is rear-ended was hit by car B (mass 1400 kg). Both cars then slide with locked wheels until the frictional force from the slick road (with a low Hk of 0.12) stops them, at distances da = 8.4 m and dg -6.2 m. a. For car A; calculate the friction force between the road and the car in the sliding distance then use work-Energy Theorem (AKE = Workner ) to find car A speed just after the collision.

Before B -da dB After B A

b. For car B; Repeat part (a).

Assuming that linear momentum is conserved during this collision, find the speed of car B just before the collision. (3pts)
