Here is the problem and answers. how do i reach the answer?

A car at the Indianapolis-500 accelerates uniformly from the pit area, going from rest to 325 km/h in a semicircular arc with a radius of 198 m.

Determine the tangential acceleration of the car when it is halfway through the turn, assuming constant tangential acceleration.

6.55m/s2

Determine the radial acceleration of the car at this time.

20.6m/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?

2.2
