A Ford Excursion A, with a mass mA = 3900 kg, traveling with a speed υA = 85 km/h collides head-on with a Mini Cooper B, with a mass mB = 1200 kg, traveling in the opposite direction with a speed υB = 40 km/h. Determine the postimpact velocities of the two cars if the impact’s coefficient of restitution is e = 0.22. In addition, determine the percentage of kinetic energy loss.
