Question

an athlete weighing 60kg runs up stairs have 10 steps. each of 0.5m in 30s calculate the power (g is 10)​

Answer 1

Explanation:

Weight of man = 60kg

Stairs have 10 step and each step is 0.5m high.

So the height of the stairs is 10*0.5= 5m

Time taken is 30s

Power = mgh/t

= (60)(10)(5)/ 30

power = 100W
