Question

A coolie lifts a box of 15 kg from the ground to a height of 2.0 m. Calculate the work done by the coolie on the
box. Given, g​

Answer 1

⛦Given:-

The work done by the coolie will be,

• Mass(m), = 15 kg,
• height (s), = 2m,

⛦To find:-

• work done by the coolie =??

$\Large{\underbrace{\sf{\purple{Required\:Answer:}}}}$

A/Q

⟼Mass(m), = 15 kg,

⟼ height (s), = 2m,

•Taking g = 9.8m/s2 

Now,

force applied, F = mg = 15 x 9.8 = 147 N

therefore,

Work done, W= Fx s= 147 X 2 = 294 N.

Thus,Work done by the collie= 294 N.

⛦Hope this helps...⛦

Answer 2

Mass(m), = 15 kg,

height (s), = 2m,

Taking g = 9.8m/s2 

Now,

force applied, F = mg = 15 x 9.8 = 147 N

therefore,

Work done, W= Fx s= 147 X 2 = 294 N.

Thus,Work done by the collie= 294 N.
