Question

What is the potential energy of a 264 kg boulder that sits on the edge of a 24 m tall cliff?

Answer 1

63.36 kJ

Step-by-step explanation:

Potential energy (PE) is the energy stored within an object, due to the object's position, arrangement or state.

Since the Boulder is now on a height , it has a potential energy

Potential Energy = mass * gravitational acceleration * height

(Assume the gravitational acceleration = 10ms⁻²)

`PE =m*g*h\\=264*10*24\\=63360 J\\=63.36 kJ`
