Question

A boy of mass 50 kg runs up a staircase of 45 steps Each in 9second. If the height of each step 15 CM find it power

Answer 1

P=FS/T
M=50kg
T=9sec
s=45*0.15m
s=6.75
A=10m/s2
P=50*10*6.75/9
P=5*675/9
P=363.5Watt

Answer 2

the formula for finding power is
P=WORK/TIME
P=337500j/405s
P=833.33watts
