A roller coaster car goes over a hill at a constant speed of12.0m/s. (a) what radius should the hill have in order for the rider in the car to feel weightless at the top of the hill?. (b)How fast should the linear speed of the roller coaster car be in order for the rider to feel two times their weight at the bottom of a dip of radius, 30.0m?
