Problem

Consider a car of mass

m

turning on a flat horizontal road with radius

r

and coefficient of friction

\mu = 1

. Let its maximum safe speed be

v_{1}

. Now consider the same car on a road banked at

\theta = 45^{\circ}

with the same radius

r

and friction coefficient

\mu = 0.5

. Let its maximum safe speed be

v_{2}

. Calculate the ratio

(v_{2} / v_{1})^{2}

.
