Question

POL.
If a man of mass 50 kg takes 60 s to climb up 20
steps, each of 15 cm height, calculate his power.​

Answer 1

Answer:

Power of the man is 25 W

Explanation:

Power = work done /time

work done  = change in Potential Energy

$= m \times g \times 20 \times h\\= 50 \times 10 \times 20 \times 0.15\\=1500J$

Power = 1500 /60

=25 W
