6 M g = M(V^2/R + g)
Cancel out the mass (M) and solve for V.
5 g = V^2/R
V = sqrt(5gR)
A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to six times her weight as she goes through the dip. If r = 20.0 m, how fast is the roller coaster traveling at the bottom of the dip?
