An engineer wants to design an oval racetrack such that 3.20 x 10° lb racecars can round the exactly 1000 ft radius turns at 101 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 0 necessary for the race cars to navigate the turns at 101 mi/h without the aid of friction. = This banking and radius are very close to the actual turn data at Daytona International Speedway, where 3.20 x 10° 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
