You are testing a new amusement park roller coaster with an empty car of mass 112 kg. One part of the track is a vertical loop with a radius of 12 m. At the bottom of the loop, the car has a speed of 25 m/s. At the top of the loop, its speed is 7 m/s. As the car rolls from the bottom to the top of the loop, how much work is done by friction. Round the final answer to a whole number.
