Answer:
5.77 × 10^2 s
Explanation:
Power is defined as the amount of work done divided by the tima taken to do that work:
[tex]P=\frac{W}{t}[/tex]
where W is the work done and t the time taken.
In this problem, we have:
- the power: [tex]P=1.51 \cdot 10^4 W[/tex]
- the work done: [tex]W=8.72 \cdot 10^6 J[/tex]
So we can re-arrange the previous equation to find the time taken:
[tex]t=\frac{W}{P}=\frac{8.72 \cdot 10^6 J}{1.51 \cdot 10^4 W}=5.77\cdot 10^2 s[/tex]
