3. Before beginning its initial descent, a roller coaster car is always pulled up the rst hill to a high hill height. Work is done on the car (usually by a chain) to achieve this initial height. A coaster designer is considering three different incline angles at which to drag a 2000kg car train to a top of the 60m high hill. In each case, the force applied to the car will be applied parallel to the hill. A critical question is: Which angle would require the most work? Analyze the data, determine the work done in each case, and answer this critical question. 35degrees 1.15x104 N 45degrees 1.41x104 N SSdegrees 1.64x104 N 3.
