## Homework Statement

A curve of radius 78 m is banked for a design speed

of If the coefficient of static friction is 0.30 (wet

pavement), at what range of speeds can a car safely make

the curve?

## Homework Equations

## The Attempt at a Solution

I calculated theta being 36.1... (85/3.6)^2/78=gTan(theta)

Now, I'm wondering how to calculate the range of acceptable velocitys.. could someone explain it to me.

I think for max velocity the centripetal force = Sliding force + Frictional force = 104kph correct?

Can explain how I need to think for minimum velocity?
