Question

A person weighing 600N runs up a flight of stairs. It takes the person 10s to get to the top. They are 6m higher at the top of the stairs. How much power was used?

Answer 1

`Power = 360W`

Step-by-step explanation:

Given

`Force = 600N`

`Time = 10s`

`Height = 6m`

Required

Determine the power used

First, we need to calculate the work done to climb the stairs.

`Word = Force * Distance`

In this case, the distance represents the height of the stairs.

So:

`Work = 600N * 6m`

`Work = 3600J`

Next, we calculate the power using:

`Power = (Work)/(Time)`

Substitute values for Work and Time

`Power = (3600J)/(10s)`

`Power = 360W`

Hence, the power used by the person is 360 watts
