feel weightlessness? A car is traveling on a road in hilly terrain. Assume the car has speed v and the tops and bottoms of the hills have the radius of curvature R. The driver of the car is most likely to feel weightlessness:
a) at the top of a hill when v is greater than the square root of gR
b) at the bottom of a hill when v is greater than the square root of gR
c) going down a hill when v equals the square root of gR
d) at the top of a hill when v is less than the square root of gR
e) at the bottom of a hill when v is less than the square root of gR
