Answer:

1620000J

Explanation:

Given parameters:

Power = 180000W

Time  = 9s

Unknown:

Work done by the engine = ?

Solution:

Power is the rate at which work is being done.

 Now,

        Power  = [tex]\frac{Work done }{time}[/tex]  

 Work done  = Power x time taken

 Work done  = 180000 x 9  = 1620000J
