Given:

The work done by the engine is: W = 635 J

The work is done over the time of: t = 45 s

To find:

The power generated.

Explanation:

Power is defined as the rate of doing work. It is the amount of energy consumed over time t.

Let P be the power, W be the work done by the engine over time t, then

[tex]P=\frac{W}{t}[/tex]

Substitute the values in the above equation, we get:

[tex]\begin{gathered} P=\frac{635\text{ J}}{45\text{ s}} \\ \\ P=14.11\text{ J/s} \\ \\ P=14.11\text{ watts} \end{gathered}[/tex]

Final answer:

The power generated by the engine is 14.11 watts.
