Banked Curve Problem

  1. Oct 5, 2011 #1
    Hey guys I know this is probably easy for most of you but I need help with a banked curve problem. The problem is as follows "Suppose you ride a bicycle in a 20-m-radius circle on a horizontal surface. The resultant force exerted by the surface on the bicycle (normal force plus frictional force) makes an angle of 15° with the vertical. (a) What is your speed? (b) If the frictional force on the bicycle is half its maximum possible value, what is the coefficient of static friction?"

    remember the formula for centripetal acceleration:

    hint: ac = v2/r

    where a is the centripetal acceleration, v is the velocity and r is the radius, that might get you started, and remember newton's second law.
