1. The problem statement, all variables and given/known data A car at the Indianapolis-500 accelerates uniformly from the pit area, going from rest to 285 km/h in a semicircular arc with a radius of 194 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? 2. Relevant equations Unknown 3. The attempt at a solution Have not attempted yet because I don't know how to start.
