Two students are watching an action film in which a car drives down a ramp onto the back of a moving lorry. Both are moving at high speed, the car slightly faster than the lory. One student complains that this is impossible because the car would not be able to stop before hitting the cab of the lorry. The car has mass 1250 kg and is moving at a speed of 28.0 ms. The lorry has mass 3500 kg and a speed of 25.5 m s¯ª. The length of the flat back of the lorry allows a braking distance of 5.0 m. By considering both momentum and energy show that the stunt is possible, provided a minimum force of about 600 N slows the car down. You should support your explanations with calculations. Treat the situation as one in which two obiects join together. Two students are watching an action film in which a car drives down a ramp onto the back of amoving lorry.

Question

Two students are watching an action film in which a car drives down a ramp onto the back of a moving lorry. Both are moving at high speed, the car slightly faster than the lory. One student complains that this is impossible because the car would not be able to stop before hitting the cab of the lorry. The car has mass 1250 kg and is moving at a speed of 28.0 ms. The lorry has mass 3500 kg and a speed of 25.5 m s¯ª. The length of the flat back of the lorry allows a braking distance of 5.0 m. By considering both momentum and energy show that the stunt is possible, provided a minimum force of about 600 N slows the car down. You should support your explanations with calculations. Treat the situation as one in which two obiects join together.
