Heya!!

given :-

• A man weighing 500 Nuns up staircases in 5sec.
• he rises up by 3.75.

To Find :-

1. What work did he do
2. What was his power

Solution :-

Power = word done /time

=force× displacement /time

=500 × 3.7/5

power = 370

Work = Force × Displacement

W = f × d

W = 500 × 3.75

W = 1875 Nm.

Hence the work is 1875 Nm. and power is 370 .
