A car with a mass of 2200kg, travelling at 60.0 km/h [E], collides with a car of mass 1300 kg that is travelling at 30.0 kg/h [E], and the two cars lock bumpers.

a) Calculate the velocity of the vehicles immediately after the perfectly inelastic collision.

b) Calculate the total momentum of the two cars before and after the collision.

c) Determine the decrease in kinetic energy during the collision.
