Answer:
The work done by the boy is 100 J
Step-by-step Explanation:
Given,
Mass = 5 kg
height = 2 m
g = 10 m / s²
Since we know,
Work done is given by :
W = m g h
where,
m is the mass f the body
h is height
g is the gravity
Substituting the values in the formula;
W = 5 * 2 * 10
W = 100 J
Hence,
The work done by the boy is 100 J
