Aroller coaster train with a mass of 500 kg stops at the top of a hill. if the hill is 110 m high, what is the potential energy of the train?

Potential energy=PE
PE=mgh
m=mass in kilograms.
g=9.8 m/s
h=height in meters

Data:
mass=500 Kg
h=110 m

PE=(500 Kg)(9.8 m/s²)(110 m)=539000 joules

The potential energy of this train would be 539000 J.
