If an 800 kg roller coaster is at the top of its 50 m high track, it will have a potential energy pf 392,000 J and a kinetic energy of 0 J. This means the total mechanical energy is 392,000 J. If the cart drops down to where its kinetic energy is now 92,000 J, how high off the ground is the cart now?

0 m

8.27 m

38.27 m
