Acar at the indianapolis-500 accelerates uniformly from the pit area, going from rest to 305 km/h in a semicircular arc with a radius of 196 m.

determine the tangential acceleration of the car when it is halfway through the turn, assuming constant tangential acceleration.
m/s2
determine the radial acceleration of the car at this time.
m/s2
if the curve were flat, 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?
