dw:1382088401350:dw Which way would the cyclist slide, and what are the two forces working against each other?

1/2 of that is right:) That half is 100 % right. Centripetal force pushing towards the center of the circle, and it's the friction that's applying the force. I drew the first diagram wrong. dw:1382107001459:dw The sum of all the forces is equal to the centripetal force \[ \sum F = F_f =m a_c = F_c \] I think I may have explained that poorly ;/ Centrifugal force doesn't really exist. The thing people call "centrifugal" force is just the tendency of your body to keep going straight while the car is turning. That's another question though :)

its B then ???

Yup yup :) \[ a_c = \frac{v^2}{r} \] so if \[F_c > F_f\] the bike skids.
