Question

A person weighing 645 N climbs up a ladder to a height of 4.55 m. What is the

increase in gravitational potential energy?

Answer 1

P.E = 2934.75

Step-by-step 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;

`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.

Given the following data;

Weight =645

Height = 4.55

`P.E = mgh`

But we know that weight = mg = 645N

Substituting into the equation, we have;

`P.E = 645 * 4.55`

`P.E = 2934.75 J`

Potential energy, P.E = 2934.75 Joules.
