Question

A force of 150N is applied at an angle of 60° to the horizontal to pull a box through a distance of 50m. Calculate the work done

​

Answer 1

Work done = 3750 Joules

Explanation:

The force acting in the body should be resolved to it's horizontal component before we can use ut to solve for the problem

Horizontal component= 150 * cos 60

Horizontal component= 150*0.5

Horizontal component= 75N

Work done= Force * distance

Work done= 75*50

Work done= 3750 Nm

Work done = 3750 Joules
