car is on a banked left curve with radius r = 100 m and banking angle θ = 20◦. What is the ideal speed to take this curve, so that no friction is needed?Explain starting with a force diagram. If the car breaks down and it is at rest on this banked angle, what coefficient of friction is needed, so that the car won’t slide down the bank? (Make a new force diagram, and be sure to explain what change.)

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.
