## Homework Statement

A 500hp Mustang is able to push this 1750kg car down a 410m drag strip in a time of 11.5s.

a) What is the work done by the car?

b) What is the average force during the car's motion.

Given: Power = 500hp = 372000w

Mass = 1750kg

Distance = 410m

Time = 11.5s

## Homework Equations

Work = Force*Distance

Power = Work/Time

## The Attempt at a Solution

Power = Force*Distance

372000w = (Force*410m)/11.5s

372000w = (410x N/m)/11.5s

Multiply each side by 11.5s

427800w = 410x N/m

Now i eliminated time, work should be 427800N, but that does not look correct. Need help and explanation here.

P.s. There will be no problems solving question b since if i get the work done I can divide it by the time.

Thanks in advance,
