A roller 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

dа ta:

mass=500 Kg

h=110 m

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

answer: The potential energy of this train would be 539000 J.
