1 The diagram shows a racing car of mass 750 kg decelerating at a constant rate on a straight and level track. A 300 m VI V2 50 m/s m/s Diagram not to scale (a) Calculate the rate of deceleration of the racing car. (b) Calculate the time taken for the car to decelerate to V₂ m/s. The racing car then travels along another straight piece of track at a velocity of V₂ m/s. As it passes point A the engine stops and the car begins to freewheel up the incline of the track. Assume there is no friction or wind resistance. original track level Point at which the car comes to rest Diagram not to scale (c) Calculate the height (h) above the original track level where the car will come to rest. The engine is then restarted and the racing car travels on a curved length of track that has a radius of 12m at a constant tangential velocity of V₂ m/s. (d) Calculate the centripetal acceleration of the racing car on the curved length of track. (e) Explain one way that friction would affect the racing car as it travels around the curved section of the track.
