Question

A person of 60kg climbs a stair case and reaches to a height of 4m.  Calculate the potential energy acquired by the person. (take g = 1Om/s2)​

Answer 1

Answer:

Potential energy=mgh

potential energy=60*10*4

potential energy=2400

pls make it brainliest answer

Answer 2

Answer:

Total work done by man in covering 20 steps =mgh=80×10×0.2×20=3200J

So, Power(P) = Time takenWork done=103200=320Watt
