I am trying to calculate the distance and speed a van was travelling behind a car when an accident occured in which the van hits the car. I know that the car brakes and skids 24metres, the van behind brakes and skids 6metres. The car was stopped prior to impact and pushed 9metres further from the impact. Deceleration on road was 6m/s. Van weighs twice the weight of car. Speed of van prior to impact was 1.5 times the speed of both vehicles after impact. What speed were both vehicles travelling and how close was the van to the car? Appreciate any help on how to work this out. Thanks

    The stopping distance d of a car after the brakes are applied varies directly as the square of the speed r. If a car travelling 70mph can stop in 270ft, how many feet will it take the same car to stop when it is travelling 60mph?
