A racecar is driven on a horizontal circular track at a constant speed of 20.0 m/s. The radius of the track is 100.0 meters and the mass of the car is 800.0 kg. a. Does the racecar accelerate and if it does in what direction is the acceleration? EXPLAIN! b. What is the centripetal force on the racecar? c. What is the value of the static frictional force between the tires and the track? d. Explain what (and why) the driver of the racecar should do if it started to rain in order to keep driving in a circle. Make sure to explain what happens to the frictional force when it begins to rain and make sure to explain how the driver’s action changes the centripetal force on the racecar.

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.
