A body of mass 45 Kg climbs up 20 steps in 20 sec if each step is 25 cm high, calculate the power used in climbing. Take g = 10m/s2 .
Height of each step = 25 cm No. of steps = 20 Total height = 25 × 20 = 500 cm = 5 m Work done = m × g × h = 45 × 10 × 5 = 2250 J Power = W o r k d o n e T i m e WorkdoneTime = ( 2250 20 ) (225020) = 112.5 Watt
