Question

A loader applied

150 N

of force to lift a stone and

1250 J

of work was done by it. How far was the rock lifted during the application of force?

Options:

A . 9.3 m

B . 10.3 m

C . 8.3 m

D . 7.3 m

Answer: Option C
:
C
Given:
Work done,

W = 1250 J

Force,

F = 150 N

Let the distance the rock was raised be

s

.
Work done is the product of force and displacement of the body along the force.

W = F s

s = \frac{1250}{150} = 8. ¯ 3 m

Thus, the rock was lifted through a distance of

8.3 m
