Question

A coolie carries a load of 50 kg on his head and walk on a label road Upto 100 metre. what is the work done by him
​

Answer 1

work = force * displacement

50kgf = 10 * 50 N

50 kgf = 500N

Work = 500 * 100

work = 50,000J or 50kJ

Answer 2

● The work done will be zero because a coolie carries a load make an angle of 90 degree wherever the 90 degree created the work done will be zero.

Proof:

W = FS Cos Q

W = FS Cos (90°)

W = FS (0)

W = 0
