A juggler is juggling a uniform rod, one end of which is coated with tar and burning! He throws it up by the opposite end such that at the moment of release, it is horizontal and its center of mass is moving vertically upward with initial velocity v0, and is rotating at angular speed ?0. To catch it, he wants to arrange that it has made an integer number of complete rotations. What should v0 be if the rod is to have made exactly n rotations when it returns to his hand?
