Answer:

Step-by-step explanation:
Given:
- mass of vehicle,

- radius of curvature,

- coefficient of friction,

During the turn to prevent the skidding of the vehicle its centripetal force must be equal to the opposite balancing frictional force:

where:
coefficient of friction
normal reaction force due to weight of the car
velocity of the car

is the maximum velocity at which the vehicle can turn without skidding.
