2. A car has the maximum centripetal acceleration 10 m/s?, so the car can turn without skidding out of a curved path. If the car is moving at a constant 108 km/h, what is the radius of unbanked curve? (5 points) Given: Centripetal acceleration (ac) = 10 m/s Car's speed (v) = 108 km/h = Find: radius (r) Solution: meters/second ac
