A 4.00−kg mass and a 3.00−kg mass are attached to opposite ends of a very light 42.0 - cm-long horizontal rod (Fig.). The system is rotating at angular speed ω = 5.60 rad/s about a vertical axle at the center of the rod. Determine (a) the kinetic energy KE of the system, and (b) the net force on each mass.

Problem 9: A uniform rod of mass mrod and length L is free to rotate about an axis at one end. A small sphere with mass msphere is attached to the other end of the rod. The rod makes an angle ϕ with vertical and is released from rest. Part (a) Determine an expression for the difference in potential energy of the system before the rod is released and the system when the sphere is at its lowest point. Your answer will be in terms of msphere , mrod , L and g. Part (b) As the system swings through the point where the rod is vertical, its angular speed is ω. Determine an expression for the rotational kinetic energy of the system as it moves through this point. Your answer will be in terms of msphere , mrod , L and ω. Part (c) Determine an expression for the angular speed at the bottom of the swing. ω =
