12. A car at the Indianapolis 500 accelerates uniformily from the pit area, going from rest to 270 km/h in a semicircular arc with a radius of 220 m. Determine the tanegntial and radial acceleration of the car when it is halfway through the arc, assuming constant tangential acceleration. If the the curve were flat, what coefficient of static friction would be necessary between the tires and the road to provide this acceleration with no slipping or skidding?"
