Question

an athlete weighing 60 kg runs up a stair case having 10 steps each of 0.5 m in 30 s. calculate his power ( g = 10s-²)

please please please help me ​

Answer 1

answer = 100 watt

EXPLANATION.

• GIVEN

an athlete weighing 60 kg runs up a stairs case

having 10 steps each of 0.5 m

time = 30 seconds.

CALCULATE HIS POWER.

mass = 60 kg

g = 10 m/s^2

height of stairs = 0.5 m X 10

work done = mgh

60 X 10 X 0.5 X 10 = 3000 joule

$\bigstar\boxed{\large \bold \green{power \: = \frac{work \: done}{time} }}$

power = 3000 / 30

power = 100 watt
