A race car accelerates uniformly as it leaves the pit area, going from rest to 305 km/h in a semicircular arc with a radius of 192 meter.
Evaluate the tangential acceleration of the car when it is halfway through the turn, assuming constant tangential acceleration.
Evaluate the radial acceleration of the car at this time.
If the curve were flat, evaluate what would the coefficient of static friction have to be between the tires and the roadbed to provide this acceleration with no slipping or skidding?
