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
Talja [164]

<u>P.E (Potential Energy) = 33868.8 J</u>

<u>Explanation:</u>

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

    = <u> 33868.8 J</u>
