The answer for the following question is explained below.
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.
