Question

An engine has 180,000 W of power and can accelerate from rest to a top speed in 9 s. How much work did the engine do?

Answer 1

1620000J

Step-by-step 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 =
`(Work done )/(time)`

Work done = Power x time taken

Work done = 180000 x 9 = 1620000J
