A 1000 kg car traveling due east at speed 20.0 m/s collides head-on with a 1500 kg light truck traveling due west at speed 10.0 m/s. a. If 50% of the car and truck system’s kinetic energy is converted to internal energy during the collision, what are the final velocities of the car and truck? b. What is the coefficient of restitution for the collision you analyzed in (a)? c. If the collision had instead been perfectly elastic, what would have been the final velocities of the car and truck? d. If the collision had instead been totally inelastic, what would have been the final velocities of the car and truck?
