## Homework Statement

A drag racer has an acceleration of 3g. What distance is needed for the car to reach a speed of 320 mi./h (143 m/s)?

## Homework Equations

v^2=vo^2+2aΔx

## The Attempt at a Solution

I decided to use m/s to make it easier.

143 m/s^2=0+2(9.8*3)Δx

20449=58.8Δx

Δx≈347.7 m

Could someone please check this? I did my best in solving it, and I checked it, but I'd like to make sure before I turn it it.
