The figure shows a weightless rod of length l which is hinged at point A with a load of mass m at its end and occupying a strictly vertical position, touching a body of mass 𝑀 Alight jerk sets the system in motion. For what mass ratio Mm will the rod form an angle alpha = 𝜋6 with the horizontal at the moment of the separation from the body. What will be the velocity v of the body at this moment Friction should be neglected.
