Suppose you ride a bicycle on a horizontal surface in a circle with a radius of 20 m. The resultant force exerted by the road on the bicycle (normal force plus frictional force) makes an angle of 15 degs with the vertical.(adsbygoogle = window.adsbygoogle || []).push({});

a. What is your speed?

b. If the frictional force is half its maximum value, what is the coefficient of static friction?

The problem is I got 2 equations that i can think of to solve for a). One equation is a=V^2/r and the other is F=mrw^2. But for the second equation I don't know the w(angular vel) and for the first I don't know a(acceleration). So how do I solve this?
