The rollercoaster in the image above initially has 200,000 J of mechanical energy. Towards the end of the ride, the roller coaster only has 50,000 J of mechanical energy. What best explains where the missing mechanical energy went?
Most of the missing mechanical energy has transferred to heat energy through friction.
Most of the missing mechanical energy has been destroyed.
W = ΔKE
The equation above means...
