Sally who is driving a 2200 kg car and rams into John who was stopped in his 1500 kg car. Sally was travelling at 36 km/h before the collision and is moving at 18 km/h afterward. All the lost kinetic energy goes into crushing John's car. It takes 50000 N to crush the car. How much shorter has the car become?
