Answer 2

Question

Find the work done by a man when he pulls a load of mass 14 Kg through a distance of 5 m.

Answer

4900 J

Explanation

Given :-

Mass (m) = 14 Kg

Height (h) - 5 m

Acceleration due to gravity (g) = 9.8 m/s

To find :-

Work done (W)

Solution :-

Work done = mgh

Work done = 100 × 9.8 × 5

Work done = 4900 Joule

∴ Work done by the man is 4900 J.
