Question

A stone of mass 6 kg is released from a height of 30 metre calculate the potential energy​

Answer 1

Answer:

P.E = 1764 Joules

Explanation:

Given the following data;

Mass = 6kg

Height = 30m

We know that acceleration due to gravity is equal to 9.8m/s²

To find the potential energy;

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;

$P.E = mgh$

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Substituting into the equation, we have;

P.E = 6 * 9.8 * 30

P.E = 1764 Joules
