A race vehicle accelerates uniformly as it leaves the pit area, going from rest to 330 kilometer per hour in a semi circular arc with a radius of 200 meter.
Find the tangential acceleration of the vehicle when it is halfway through the turn?
m/s2
Find the radial acceleration of the car at this time.
If the curve were smooth, find what would the coefficient of static friction have to be between the tires and the roadbed to provide this acceleration with no skidding or slipping?
