(1) car skids 85m before striking a parked car in the rear with a velocity of 15ms-1 the cars become locked?
together and skid for a further 5.2 m before coming to rest the mass of car 1 is 1350kg and car 2 has a mass of 1520kg
what is the average frictional force between the road and the cars that bring them to a rest?
(2)
