Answer:
The roller coaster has potential energy
P.E = 95863.6 Joules
Step-by-step explanation:
Potential energy is the energy contained in an object that is not moving. Since the roller coaster is on a fixed position at the top of the hill, it therefore has potential energy.
Given
Mass M = 134kg
Height h = 73 meters
Acceleration due to gravity g = 9.8m/s^2
Potential energy = Mgh
P.E = 134 x 9.8 x 73
= 95863.6 Joules
