An engineer wants to design an oval racetrack such that 3.20 x 10³ lb racecars can round the exactly 1000 ft radius turns at 104 mi/h without the aid of friction. She estimates that the cars will round the turns at a maximum of 175 mi/h. Find the banking angle necessary for the race cars to navigate the turns at 104 mi/h without the aid of friction. 0= This banking and radius are very close to the actual turn data at Daytona International Speedway, where 3.20 x 10³ lb stock cars travel around the turns at about 175 mi/h. What additional radial force is necessary to prevent a race car from drifting on the curve at 175 mi/h? radial force: N

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.
