Question

If a curve with a radius of 88m is perfectly banked for a car traveling 75km/h, what must be the coefficient of static friction for a car not to skid when traveling at 95km/h? ac=v^2/r

Answer 1

\[V=\sqrt{\mu*r*g}\]

\[v^2 = \mu*r*g\]

\[\mu=\frac{ v^2 }{ rg }\]

Answer 2

Just Substitute and Find it out..)
