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.
