Question

calculate the power devloped by a 110kg man climbilNg vertical stair at the rate of 2 metre per seconde where g equal to 9.8 metre per seconde sqaure

Answer 1

Hi friend,

Power = work done/time

Time = velocity /acceleration

Time = 2/9.8

Time =0.20 secs

Work done = kinetic energy

W= 0.5 ×110×4

W= 220J

Power = 220/0.20

Power =1100 watt .

Hope this helped you a little!!!
