    support force is an odd term, but I think what it wants you to do is to calculate the centripetal force on the person.

    If travelling on the flat, the push from the train on the person would just need to balance the weight, but now it also needs to provide a centripetal force.

    You have an acceleration from b (i)

    I would use F=ma with the mass of the person (which you can calculate from the weight)
