How friction force is provided on vehicle taking turn on level circular path ?

Write value of safe speed on frictionless level circular track.

Write equation of maximum safe speed on level circular track

A train of length l is moving with a constant speed v circular track of radius R, the engine of the train emits a whistle of frequency f_(0) . Find the frequency heard by a guard at the rear end of the train.

On which road we get maximum speed ? Circular road with slope or level circular road

A pendulum is suspended from the roof of a rall road car. When the car is moving on a circular track the pandulum inclines:

The centripetal force on a particle moving in a uniform circular motion on a horizontal circle of radius r is (-sigma)/(r^(2)) , then find the mechanical energy of this particle .

The driver of a bus travelling with a speed 'v' suddenly observes a wall in front of his bus at a distance 'a'. Father of this driver, who was also a driver, had advised him to take circular turn to avoid hitting in such a situation. However, the driver in question decides otherwise by using his own wisdom. He applies brakes as hard as possible without taking a circular turn, then :

Write equation of centripetal acceleration and centripetal force for uniform circular motion.

Write the formula for the maximum permissible speed of a vehicle moving on smooth circular balanced tracks.
