(a)[2]
Calculate the momentum of car A from the information given.
(b(i))[1]
Calculate the momentum of car B just after the collision.
(b(ii))[1]
Determine the average impulse received by car B during the collision.
(b(iii))[2]
Calculate the average resultant force acting on car B during the collision.
(c)[2]
Modern cars are built so that, in a collision, the front of the car crumples and the contact time becomes longer. Explain why increasing the contact time helps the people inside the car.
