A rollercoaster car with a mass of 500 kg is released from the top of a hill with a height of 50 m. As the car descends down the hill, it increases its speed from 0 m/s to 30 m/s. If the total distance travelled by the rollercoaster is 100 m, what is the total work done by gravity on the rollercoaster car?
