Suppose you are driving through a valley whose bottom has a circular shape. The radius of the circle is R = 40m. If your mass is M = 70kg, and your car is traveling at a constant speed of V = 20m/s, What is the magnitude of the normal force FN exerted on you by the car seat as you drive past the bottom of the hill?
1) FN = 980 N
2) FN = 1021 N
3) FN = 1386 N
4) FN = 1462 N
5) FN = 1525 N
