Answer:
It would take 16.7 s for the work to be done by the engine.
Explanation:
From the question, given: Power = 390.3 kW
Work to be done = 6.5 x [tex]10^{6}[/tex] J
But, power and work done with respect to time, has a relationship of:
Power = [tex]\frac{work done}{time}[/tex]
So that,
time = [tex]\frac{work done}{Power}[/tex]
Thus,
time = [tex]\frac{6.5*10^{6} }{390.3*10^{3} }[/tex]
= 16.6539
time = 16.7 s
Time required is 16.7 seconds.
Thus, it would take 16.7 s for the work to be done by the engine.
