In a scene in an action film, a car with a mass of 2200 kg, travelling at 60.0 km/h [E], collides with a car of mass 1300 kg that is travelling at 30.0 km/h [E], and the two cars lock bumpers. A (a) Calculate the velocity of the vehicles immediately after the perfectly inelastic collision. [ans: 14 m/s [E]]
(b) Calculate the total momentum of the two cars before and after the collision. [ans: 4.8 x 10-kg-m/s]
(c) Determine the decrease in kinetic energy during the collision. [ans: 2.8 x 10^J]
