A cyclist rides along a circular path in a horizontal plane where the coefficient of friction varies with distance from the centre O of the circular path as mu = mu_(0)(1-(r)/(R)) where R is the maximum distance up to which the road is rough Find the radius of the circular path along which the cyclist can ride with maximum velocity. What is this maximum velocity ?

Civil engineers bank a road to help a car negotiate a curve. While designing a road they usually ignore friction. However, a young engineer decided to include friction in his calculation while designing a road. The radius of curvature of the road is R and the coefficient of friction between the tire and the road is mu . (a) What should be the banking angle (theta_(0)) so that car travelling up to a maximum speed V_(0) can negotiate the curve. (b) At what speed (V_(1)) shall a car travel on a road banked at theta_(0) so that there is no tendency to skid. (No tendency to skid means there is no static friction force action on the car). (c) The driver of a car travelling at speed (V_(1)) starts retarding (by applying brakes). What angle (acute, obtuse or right angle) does the resultant friction force on the car make with the direction of motion?

What will be the maximum speed of a car when it safely driven along a curved road of radius 100 m ? (mu=0.2)
