Grade 11Modern Physics

A weightless rod of length l with a small load of mass m on it''s one end is hinged at point A as in the figure and occupies a strictly position as shown in figure touching the body of mass M. A light jerk set the system in motion. For what ratio of M/m will the rod form the angle of 30 with the horizontal. At the the moment of separation from the body what will be velocity of body at this moment. Friction is neglected. figure is like a rod having mass in shape of a ball on upper end is touched with a rctangular block having it''s lenght along rod.

Hello
Your figure is not present here.
This seems like a work energy problem.
So conserving momentum and Energy of the system should do enough for the answer.
