A small block with mass m is placed inside an inverted cone that is rotating about a vertical axis such that the time for one revolution of the cone is T (Fig. 5.83). The walls of the cone make an angle p with the vertical. The coefficient of static friction between the block and the cone is μ. If the block is to remain at a constant height h above the apex of the cone, what are the maximum and minimum values of T?
