Question

A Man Holding 7N Weight Moves 7M Horizontal And 5M Vertical , Find The Work Done?

Answer 1

According to the question, we have;

Weight being carried by the man = 7 N

Total distance covered by him = 7 m + 5 m = 12 m (∵ the man moved 7 m horizontally and 5 m vertically)

To derive the work done, we use the formula given below;

Work done = Force × Distance covered

= (7 × 12) J = 84 J

Ans) The work done by the man while holding a weight of 7 N and travelling a total distance of 12 m is 84 joules
