Answer:
It takes 6 seconds
Explanation:
Power is the rate of doing work. Power used or dissipated can be calculated as the relationship between the work done and the time it took to do it. That's why its units are also J/s.
Mathematically:
[tex]Power=\frac{Work}{time}[/tex]
In this case, we know about the Power and the work done, so we can calculate the time it took. Solving for time:
[tex]time=\frac{Work}{Power}[/tex]
Plugging in the values:
[tex]time=\frac{1800J}{300J/s}\\time=6s[/tex]
