Question 16 (1 point) Saved A roller coaster of mass 500 kg is at its highest point travelling at a velocity of 4 m/s. The loop is 15 meters tall. Assuming 5000J of energy is lost between the highest and lowest points of the loop, how fast is the roller coaster travelling when it reaches the lowest point of the loop? 0 8.4 m/s @ 17.0 m/s O 22.5 m/s O 28.0 m/s
