Again, energy is the most direct way to understand this problem. This is the principal mode of operation of roller coasters (without any propulsion systems installed in the cars) which allows them to negotiate a series of slopes and hills without running out of energy. The safety features on a roller-coaster have a specific range of height and weight that passengers must be within. If centripetal force is directed toward the center, why do you feel that you are thrown away from the center as a car goes around a curve?

Because essentially no energy is lost from the system (you are told friction and air resistance are negligible,) the amount of energy in the system remains constant throughout. Express your answer numerically, in meters. It is equally correct to include it. (b) How far does he travel? The existence of a maximum weight was mentioned in passing but I don't think a figure was stated (I'm guessing there's a figure written somewhere for riders and if you're over 200 kg or whatever you're out of luck.).

We are given complete information about the energy of the roller-coaster at Point A and are asked about the force required to stop it by Point D. Therefore, the second question can be answered by comparing A and D. Because the energy in the roller-coaster is the same from A to C, it is equally fine to compare B to D or C to D (if you solve for vC first.).
