Question

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?

Answer 1

539,000 J

Step-by-step explanation:

The equation for finding potential energy is PE = m × g × h, where m = mass (kg), g = gravity (9.8
`m/s^2`), and h = height (m).

So, multiply [500 kg], [110 m], and [9.8
`m/s^2`], so the answer would then be 539,000 J.

Answer 2

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

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