Final answer:

The power used is 15 watts.

Step-by-step explanation:

To calculate power, we use the formula:

Power (P) = Work (W) / Time (t)

In this case, the work done is 45J and the time taken is 3 seconds. Plugging these values into the formula:

Power (P) = 45J / 3s = 15W

Therefore, the power used is 15 watts.
