A Juggler is juggling a uniform rod one end of which is coated in tar and burning. He is holding the rod by the opposite end and throws it up so that, at the moment of release, it is horizontal, its CM is traveling vertically up at speed 120 and it is rotating with angular velocity coo. To catch it, he wants to arrange that when it returns to his hand it will have made an integer number of complete rotations. What would 120 be, if the rod is to have made exactly n rotations when it returns to his hand
