Question 21 (1 point) A roller coaster with a mass of 500.0 kg starts from a height of 27.0 meters with a speed of 5.2 m/s. It descends to a height of 2.00 meters before it starts back up. Some energy is loss to the work due to friction. The speed at the bottom of the ramp is 22.0 m/s. How much energy was lost to friction? Your
