1. A 12 kilogram block is sitting on a platform 24 m high. How much Potential energy does

Mazyrski [523]

The amount of potential energy the block contains is 2,822.4 Joules

<u>Given the following data:</u>

Mass of block = 12 kg

Height of platform = 24 meters.

We know that the acceleration due to gravity (g) of an object on planet Earth is equal to 9.8 $m/s^2$ .

To determine the amount of potential energy the block contains:

Mathematically, potential energy (P.E) is given by the formula;

$P.E = mgh$

Where:

m is the mass of object.

g is the acceleration due to gravity.

h is the height of an object.

Substituting the parameters into the formula, we have;

$P.E = 12 \times 9.8 \times 24$

Potential energy (P.E) = 2,822.4 Joules
