Answer:

the power used by the person is 17 W.

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;

[tex]P = FV\\\\P = F \ \times \ \frac{d}{t} \\\\P = 51 \ \times \ \frac{5}{15} \\\\P = 17 \ W[/tex]

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