## Homework Statement

Determine the radius of a highway curve which has a banking angle of 6% over which vehicles will travel at 120km/h

## Homework Equations

I've started with:

Fx = -F

_{centripetal}= (mv

^{2})/r = -Fnsin6

(mv

^{2})/2 = mgsin6

converted my km/h => m/s .... 33.3m/s

## The Attempt at a Solution

pretty much just subbed in the values

-Fc = -Fnx

-mv

^{2}/r = -mgsin6

-33.3

^{2}/r = -9.81sin6

-33.3/-9.81sin6 = r

r = 1.08km?

is this correct?
