Question

In Fig. 6-41, a car is driven at constant speed over acircular hill and then into a circular valley with the same radius.At the top of the hill, the normal force on the driver from the carseat is 0. The driver's mass is 64.7 kg. What is the minimummagnitude of the normal force on the driver from the seat when thecar passes through the bottom of the valley? i got 1268... but its not the right anwser..
