Question

A man of mass 30 kilograms
climbs the stairs of height
5 metess in 4 second the power
Olet put produced will be​

Answer 1

Given that,

mass of man, m = 30 Kg

height of stairs, h = 5 m

acceleration due to gravity, g = 10 m/s²

Now,

Potential energy at that height = mgh

=> P.E = 30 × 5 × 10

=> P.E = 1500 Joules

Now,

Power = Energy / Time

Power = 1500/4

Power = 375 Watts

Power produced is 375 W
