Hello I am in year 11 and i am not sure how to do this question:
A motor vehicle has a kerb weight of 1500kg and is moving with a velocity of 50 kilometres per hour. The mass of the driver is 80kg and there are no other passengers in the motor vehicle. This motor vehicle collides head on with a concrete wall (2 metres high and 1 metre thick) and comes to rest in 0.15 seconds.
Critically evaluate the change of energy which occurs during this collision.
