Kinetic energy is conserved

Reference no: EM13537668

On a level road, a truck collides head-on with a compact car. The fenders lock and the two cars travel as one unit after the collision. We know that during the collision:

1) Kinetic energy is conserved.
2) Kinetic energy and momentum are conserved.
3) Momentum is conserved.
4) The momentum of the truck is conserved but the momentum of the car is not conserved.
