Homework Help: Create an equation

  1. Oct 21, 2007 #1
    1. The problem statement, all variables and given/known data
    A circular curve of radius R in a new highway is designed so that a car traveling at speed v can negotiate the turn safely on glare ice (zero friction). If a car travels too slowly, then it will slip toward the center of the circle. If it travels too fast, then it will slip away from the center of the circle. If the coefficient of static friction increases, a car can stay on the road while traveling at any speed within a range from vmin to vmax. Derive formulas for vmin and vmax using mu for µ, and v, R, and g as appropriate.

    2. Relevant equations
    I think it is Summation of Fr=mAr=mV^2/r

    3. The attempt at a solution
    I tried various formula but it turn out to be wrong. I cant seem to fit in the coeffient of friction.
