A motorbike performs the'' loop the loop' 'stunt where it travels in vertical circular motion. At the top of the circle the centripetal force is fn+mg=mv^2/r. It must have a minimum speed to stay on the track. The book says to minimise velocity the normal force has to equal zero. My question is how can a normal force be zero if something has to be oppose the static frictional force.
