A bug of mass m crawls with a constant speed v' along the spoke of a wheel that is rotating with angular velocity ?. The plane of the wheel is horizontal.
a) Find all apparent forces acting on the bug if the spoke of the wheel is directed radialy outward from the center. Indicate clearly the direction of all of these forces.
b) Find how far the bug can crawl from the center of the wheel before it starts to slip. The coefficient of static friction between bug and spoke is µ_s.
