A car at the Indianapolis 500 accelerates uniformly from the pit area, going from rest to 350km/h in a semicircular arc with a radius of 210m .
A) Determine the tangential and radial acceleration of the car when it is halfway through the arc, assuming constant tangential acceleration.
B) If the curve were flat, what would the coefficient of static friction would be necessary between the tires and the road to provide this acceleration with no slipping or skidding?
