3.) frank does 2400j of work in climbing a set of stairs. if he does the work in 6 seconds, what is his power output?

Explanation:

Step1: Recall the power formula

Power ($P$) is defined as the work done ($W$) divided by the time taken ($t$), so the formula is $P = \frac{W}{t}$.

Step2: Identify given values

We know that the work done $W = 2400\,\text{J}$ and the time taken $t = 6\,\text{s}$.

Step3: Substitute values into the formula

Substitute $W = 2400\,\text{J}$ and $t = 6\,\text{s}$ into $P = \frac{W}{t}$, we get $P = \frac{2400}{6}$.

Step4: Calculate the result

$\frac{2400}{6} = 400\,\text{W}$.

Answer:

400 watts
