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.
Step-by-step 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

Substitute the values in the above equation, we get:

Final answer:
The power generated by the engine is 14.11 watts.
