Question

A man having mass 40 kg climbs the staircase of 6 meter height in 5 seconds
then calculates his power.

Answer 1

Answer:

Explanation:

Given,

mass(m) = 40kg

Distance(s) = 6m

time(t) = 5s

Let's take :-

Gravitation(g) = 10m/s^2

To Find :-

Power

Solution :-

Formula Required :-

1) P = w/t = FS/t

2) F = mg

Let's do :-

F = mg

$= 40\times 10$

= 400N

$P = \dfrac{400\times 6}{5}$

$=80\times 6$

= 480Watts.
