If it takes 5 seconds for you to do 1000j of work's what is your power output?

Power is defined as the rate at which work is done, and it is calculated by dividing the amount of work done by the time it takes to do that work. In this case, if you do 1000 joules of work in 5 seconds, your power output would be 200 watts (1000 joules / 5 seconds = 200 watts). This means you are exerting a power of 200 watts to perform the work.
