Question

An engine creates a 2230 N force that pushes a car forward 58.3 m in 9.40 s. how much power does the engine produce? (unit = W)

Answer 1

Given :

An engine creates a 2230 N force that pushes a car forward 58.3 m in 9.40 s.

To Find :

How much power does the engine produce in Watt.

Solution :

We know, Work done is given by :

`W = F.d\\\\W = 2230 * 58.3 \ J\\\\W = 130009\ J`

Now, Power is given by :

`Power = (Work \ Done)/(Time \ Taken)\\\\P = (130009)/(9.4)\ W\\\\P = 13830.74\ W`

Therefore, power produced by engine is 13830.74 W.
