Answer:

P = 15 [W]

Explanation:

Power is defined as the relationship between work over a certain time.

In this way we must calculate the work which is defined as the product of force by distance.

[tex]W=F*d\\W=75*20\\W=1500[J][/tex]

And the power.

[tex]P=W/t\\P=1500/100\\P=15[W][/tex]

Power given in units of watts.
