Question

How much power would it take to move a chair 5 meters in 15 seconds using a force of 51 newtons?

Answer 1

the power used by the person is 17 W.

Step-by-step explanation:

Given;

applied force, F = 51 N

distance through which the chair is used, d = 5 m

time of motion, t = 15 s

The power used by the person is calculated as;

`P = FV\\\\P = F \ * \ (d)/(t) \\\\P = 51 \ * \ (5)/(15) \\\\P = 17 \ W`

Therefore, the power used by the person is 17 W.
