A pendulum with string length 1.5 m is dropped from rest. If the mass at the end of the pendulum is 23 kg, what is its initial potential energy?

P.E = 338.1 Joules

Explanation:

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

Where, P.E represents potential energy measured in Joules.

Given the following data;

Height = 1.5m

Mass = 23kg

Acceleration due to gravity, g = 9.8m/s² (since it's falling from rest)

Substituting into the equation, we have;

P.E = 338.1 Joules
