Question

What is the potential energy of a falling rock if it has a mass of 64 kg and fell from a height of 54 m

Answer 1

P.E (Potential Energy) = 33868.8 J

Step-by-step explanation:

The formula to calculate Potential energy is:

PE = mgh

where PE = potential energy

m = mass of an object

g = acceleration due to gravity

h = height of the object

Here, m = 64 kg

g = 9.8
`m / s^(2)`

h = 54 m

So, substituting the values in the formula:

PE = mgh

= 64 × 9.8 × 54

= 33868.8 J
