A girl of mass 62kg ran up a flight of 12 steps each 7cm high is 5 second.fine the power she used (g=10ms~2)
Answered by oobleck
power = force*distance/time = mgh/t
(62kg * 10N/kg) * (12steps * 7cm/1step * 1m/100cm)/5s = 10.416W

M=62kg
H=0.07*12=0.84m
T=5s
g=10ms^-2
P=mgh/t
=62*10*0.84/5
=104.16watts

Answer
Answer
m=62kg
h=12×7-84cm to m=0.84m
t=5s
g=10ms–²
Workdone=mgh=62×10×0.84=520.8J

To find power, we can use the formula:

power = work done / time

So,

power = 520.8 J / 5 s
power = 104.16 W

Therefore, the girl used a power of 104.16 watts while running up the flight of stairs.
