Two curves on a highway have the same radii. However, one is
unbanked and the other is banked at an angle of 
degrees. A car can safely travel along the
unbanked curve at a maximum speed 
under conditions when the coefficient of
static friction between the tures and the road is 
. The banked curve is frictionless, and the
car can negotiate it at the same maximum speed . Find the coefficient of static friction
between the tires and the road.
