A rollercoaster vehicle has a mass of 506 kg when fully loaded with passengers (see figure).
(a) If the vehicle has a speed of 22.0 m/s at point A, what is the force of the track on the vehicle at this point?
(b) What is the maximum speed the vehicle can have at point B in order for gravity to hold it on the track?

I have no idea what Point A , B are.

point A, r=10m and point B, r=15m

1.) ((m*v^2)/r1)+ma
