If a car takes a banked curve at less than a given speed, friction is needed to keep it from sliding down towards the inside of the curve. Calculate the minimum speed in meters per second, required to take a 108 m radius curve banked at 12° so that you don't slide inwards assuming there is no friction. What is the minimum coeficient of friction needed for a driver to take the same curve at 21 km/h?

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
