The roller coaster car has a mass of 500 kg. It is pulled from position 1 to 2 (30 m) by a motor. At the top of the ride, the vertical distance from top to bottom is 20 m. The motor pulls the car with a 4000 N force. Calculate the gravitational potential energy of the car at the top of the ride. A) 100,000 J B) 120,000 J C) 800,000 J D) 90,000 J
