A 720 kg roller-coaster starts off from Location A. Assuming friction does not impede the car's motion, what will be the change in its potential energy by moving from Location A to Location B

Verified Answer :

We know, Potential Energy = m g h
Here, mass & gravity would be same, but their height will change so it will be:

ΔU = U₂ - U₁
ΔU = mgh₂ - mgh₁
ΔU = mg (h₂ - h₁)

Hope this helps!

The correct answer is: 6.0 x 10^5 J
