If you answer more than two questions, only the first two attempted questions will be marked. Each question carries 20 marks. Question B1 Car A with mass 1200 kg stops at a traffic light and is bumped by car B with mass 1600 kg, as shown in Figure BI. Both cars then slide with locked wheels until the frictional force from the road stops them at distances da = 10 m and de = 5 m. Given that the coefficient of kinetic friction between the cars and the road is uk = 0.6. Before After Do Figure BI (a) Calculate the speeds of cars A and B at the start of the sliding, just after the collision. (8 marks) (b) Calculate the speed of car B, just before the collision. (6 marks) (c) Calculate the kinetic energy loss during the collision. (6 marks) O 28C AR ~ OUR 14:33 18/5/2022 18
