Question

A frontend loader applied 150 N of force to lift a stone. If a work of 1250 joules was done in total, then what is the distance moved by the stone?

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

Answer 1

The correct option is D

8.3 m

Given, Work done = 1250 J = 1250 N m
Force = 150 N

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.
