Question

Driving in your car with a constant speed v, you encounter a bump in the road that has a circular cross section. The radius of curvature of the bump is 35.At what speed must you go over the bump if people in your car are to feel "weightless"?

Answer 1

Centrifugal and Gravity forces cancel, so\[F_c=F_g\]\[{mv^2 \over r}=mg\]\[v=\sqrt{rg}=\sqrt{35*9.8}=18.52m/s\]
