Question

You lift a chair that weighs 50 N to a height of 2 m in 1.5 s. You then hold it in the air fo

5 s. How much power did you exert moving the chair?

Answer 1

The power exerted in moving the chair is approximately 66.67 Watts.

Step-by-step explanation:

To calculate the power exerted in moving the chair, we need to use the formula:

Power = Work / Time

First, we need to calculate the work done in lifting the chair:

Work = Force * Distance

Given that the chair weighs 50N and it was lifted to a height of 2m, the work done is:

Work = 50N * 2m

= 100 J

Next, we can calculate the power:

Power = 100 J / 1.5 s

= 66.67 W

Therefore, the amount of power exerted in moving the chair is approximately 66.67 Watts.
