A car moves with constant speed of 10 m/s in a circular path of radius 10m. The mass of the car is 1000 kg. Who or what is providing the required centripetal force for the car? How much is it?
The required centripetal force is provided by the normal reaction of the ground.
Now, according to the question;
Radius of circular path (r) = 10 m.
Mass of the car (m) = 1000 Kg.
Speed of the car (v) = 10 m/s.
The figure below describes the situation.
The required centripetal force is F = 
⇒ F = 
⇒ F = 
The centripetal force required for the car is 104 N .
