A hollow ball with mass m = 0.1 kg and radius R = 5 cm is sliding across a flat frictionless surface with an initial speed v = 5 m/s. At x = 0, it encounters a patch of ground with coefficient of kinetic friction μk = 0.3. The ball is initially not rotating but the friction causes it to start spinning. How far will it travel along that surface before it begins rolling without slipping. For this problem, assume...

A circular annulus, of mass M, inside radius a and outside radius 2a, is given an angular speed w about an axis, through its center perpendicular to its plane, which is horizontal. It is then gently placed on a rough horizontal plane, the coefficient of friction being u. Show that the annulus will start rolling without slipping after a time (10aw/13ug). The experiment is repeated in a space craft on a circular orbit around the earth. State giving reasons, whether...

A 3 kg disk of radius 0.25m is rotating freely at an angular speed of 100 rad/s on a shaft passing through the center of mass of the disk. A 2 kg solid ball of the same radius, initially not rotating, slides down the shaft(the shaft passes through the ball's center of mass) and is coupled to the disk. Assuming that the rotational inertia of the shaft is negligible, a) What is the angular speed of the disk-ball combination, b)...
