Appropriate Question:-

The output for a 60kg woman who runs up a 3m high flight of stairs in 3.5 sec.starting from rest but having a final speed of 2 m/s.

Given:-

Mass of woman=m=60kg.

Height=h=3m

Time=t=3.5secs.

To find :-

Here we want to calculate the output for a woman

Here first we should calculate work done first.

work \: done = mghworkdone=mgh

Applying the values,

work \: done = 10 \times 60 \times 3workdone=10×60×3

Work done= 1800Joule.

Now , lets calculate power,

power = \frac{workdone}{time \: taken} power=

timetaken

workdone

Now,

Applying the values ,

power = \frac{1800}{3.5} power=

3.5

1800

Power =514.2857 watt.

Hope it helps u mate .
