A car – truck crash can be modelled as a ‘head-on’ collision between a truck of mass 4000 kg travelling at 15 m s–1 and a stationary car of mass 1000 kg. After the collision the truck continues moving forward at 10 m s–1. Question 103 (1998 Question 4) Calculate the speed of the car immediately after the collision. Question 104 (1997 Question 9) Modern cars are designed to crumple progressively (crush over a period of time) when they have a head-on collision as described above. Using suitable physics, explain the purpose of the crumple section of the car. Your answer should include the ideas of force and momentum.
