How much work does a 65 kg person climbing a 2000 m high cliff do?

The answer for the following question is explained below.

Therefore the work done is 130 kilo Joules.

Explanation:

Work:

A force causing the movement or displacement of an object.

Given:

mass of the person (m) = 65 kg

height of the cliff (h) = 2000 m

To calculate:

work done (W)

We know;

According to the formula:

W = m * g * h

Where;

m represents mass of the person

g represents the acceleration due to gravity

where the value of g is;

g = 10 m / s²

h represents the height of the cliff

From the above formula;

W = 65 * 10 * 2000

W = 130,000 J

W = 130 Kilo Joules

Therefore the work done is 130 kilo Joules.
