A 1600 kg car is traveling over a hill that has a radius of curvature of 25 m. The car is slowing down as it goes over the hill. It slows down at a constant rate from a speed of 25 m/s to a speed of 10 m/s over a distance of 50 m ending at the top of the hill. The net acceleration of the car at the top of the hill is most nearly 5.3 m/s/s O 9.3 m/s/s 4.0 m/s/s 26 m/s/s O 6.6 m/s/s
