Maximum velocity-

A circular track of radius $300$ m is banked at an angle $\frac{π}{12}$ radian. If the coefficient of friction between wheel of a vehicle and road is $0.2$ , the maximum safe speed of vehicle is :
28 $m s^{- 1}$
38 $m s^{- 1}$
18 $m s^{- 1}$
48 $m s^{- 1}$

Maximum velocity,

A circular track of radius 300 m is banked at an angle π12 radian. If the coefficient of friction between wheel of a vehicle and road is 0.2, the maximum safe speed of vehicle is :28 ms−138 ms−118 ms−148 ms−1
