Question

A front end loader applied a force of 150 N to move a rock such that 1250 J of work is done. How far is the rock moved?

• 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

Given:
Force = 150N
Work done = 1250 J
Work done = Force $\times$ Displacement
1250 = 150 $\times$ Displacement
Displacement = $\frac{1250}{150}$ = 8.33 m
Thus, the rock was moved by a distance of 8.33 metres.
