A 31,000 lb truck A and a 3970 lb sports car B collide at an intersection. At the moment of the collision the truck and the sports car are traveling with speeds = 60 mph and = 50 mph, respectively. Assume that the entire intersection forms a horizontal surface. Letting the line of impact be parallel to the ground and rotated counterclockwise by α = 20° with respect to the preimpact velocity of the truck, determine the postimpact velocities of A and B if the contact between A and B is frictionless and the COR e = 0.1. Furthermore, assuming that the truck and the car slide after impact and that the coefficient of kinetic friction is μk = 0.7, determine the position at which A and B come to a stop relative to the position they occupied at the instant of impact.
