Question

Before beginning its initial descent, a roller coaster car is always
pulled up the first hill to a high initial 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 the 2000-kg car train to the top of the 60-meter
high hill. In each case, the force applied to the car will be applied
parallel to the hill. Her 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.
