A small bead of mass M is launched from the end of a horizontal rod at a speed u along rod having same mass M. The rod is free to rotate in a vertical plane about a end. Simultaneously the rod is given a angular velocity omega as shown in the figure. Find the angular acceleration of the rod. [The rod is hinged at an end]
