Another Physics Question?
A roller-coaster track has six semicircular "dips" with different radii of curvature. The same roller-coaster cart rides through each dip at a different speed.
A) For the different values given for the radius of curvature R and speed v, rank the magnitude of the force of the roller-coaster track on the cart at the bottom of each dip.
Don't get this, please help

the centripetal force is m v^2 / r . m does not change. Nor does the force of gravity. So calculate the values of v^2 / r for each scenario. The largest value gives the largest force, the lowest value gives the lowest force.
