You push on a box with a Power of 6.5 Joules per second. How much work was done after 3 seconds?

To calculate the work done, we need to use the formula:

Work = Power x Time

Given that the Power is 6.5 Joules per second and the time is 3 seconds, we can plug in these values to the formula:

Work = 6.5 J/s x 3 s
Work = 19.5 Joules

Therefore, after 3 seconds, a total of 19.5 Joules of work was done on the box.
