Question: what is its centripetal acceleration in g's?
Answer: A curve that as a posted speed limit of 25 m/s and has a radius of 50 m requires a centripetal acceleration of 6.5 m/s2. In terms of g's this is 0.66 g's, (6.5/9.8 = 0.66 ). The centripetal force needed for a car to make it around a flat corner supplied by the friction between the car's tires and the road.
