A roller coaster is at the top of a 73 m hill and weighs 134 kg. The coaster (at this moment) has what energy. Calculate it

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
