Work and Energy:

A roller coaster must do work raising its cars to the highest point on the ride. From there, the cars coast at varying speed until they return to the starting point. Suppose a loaded roller coaster car must be pulled 3.00 x 10^2 m from the ride's starting point on the top of the first rise. If 2.13 x 10^6 J of work must be done on the car during this stage of ride, how large is the force exerted on the car by the raising mechanism?
