Calculate velocity and acceleration during collisions.

A small car of mass 500kg is travelling at 120km/h when it hits stationary truck (of 1.5 tonne mass) head on. The small car rebounds and travels in the opposite direction at 40km/h. The collision takes 1.2 seconds.
a) Calculate the final velocity of the once stationery truck.
b) Calculate the average acceleration on the small car, during the collision.
c) Is the kinetic energy conserved? If yes, show using calculations. If not, explain what is happening.
