You are an insurance investigator at the scene of a car accident. From witness descriptions, it is clear that Car A (of mass M_A) started skidding and slid a distance L (which you measure from the tire marks at the scene) and collided with car B (of mass M_B) which was at rest at a stoplight. The two cars after they collided both slid a distance L_slide which you also measure from the scene of the accident. Given the coefficient of kinetic friction between tires and the road, mu_k (as well as M_A, M_B, g, L_slide and L) can you calculate how fast car A was travelling when it started to slide - which would be relevant for determining if car A was speeding before the collision.
