## Homework Statement

The task is to design a highway. I did a similar project last year but I have completely forgotten and have no clue what to do.

You have to design a banked, circular, clockwise highway exit. you knwo you have 5000 sq. meters. of land to build it on..you also know that the average stretch before entering a highway exit is typically 300 m. you know the highways speed limits are 100 km/h but can reach 120 km/h (27.777 m/s and 33.333 m/s). you also know that vehicles can range in weight from 100 kg to 100,000 kg.

We have to determine the speed limit for the curve as well as determine the angle of the bank on the curve. and aslo take into account different road conditions such as rain and snow.

I've been looking at the problem for hours and tried some stuff but I only got ridiculous numbers because i used the highways speed limits because I don't know what the speed limit of the curve should be. I don't know what to do

## Homework Equations

I don't even know

I think v= √g*r*tanθ

I have none for you right nowplease give me some guidance (I shouldn't have taken physics I'm so helpless)
