A Ford Excursion A, with a mass mA = 3900kg and traveling with a speed vA = 25 km/h, collides head-on with a Mini Cooper B, with a mass mB = 1200 kg, traveling in the opposite direction with a speed vB = 15 km/h. Model the impact of A and B as an unconstrained direct central impact of particles and determine the time needed for each car to stop if the cars slide after impact with μk = 0.8 and if the impact’s COR is e = 0.1.
