Question

A loader applied 150 N of force to lift a stone and 1250 joules of work was done. How far was the rock lifted?

• A. 9.3 m
• B. 10.3 m
• C. 8.3 m
• D. 5.3 m

Answer 1

The correct option is C

8.3 m

Here,
Force = 150 N
Work done = 1250 J

Work done = Force $\times$ displacement

1250 = 150 $\times$ displacement

$\text{Displacement}=\frac{1250}{150}=\text{8.33 m}$

Thus, the rock was lifted through a distance of 8.33 metres.
