A race vehicle accelerates uniformly as it leaves the pit area, going from rest to 320 km/h in a semicircular arc with a radius of 198 meter.
Find the tangential acceleration of the vehicle when it is halfway through the turn, assuming constant tangential acceleration.
Find the radial acceleration of the vehicle at this time.
If the curve were flat, find 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?
