50. (II) A pendulum consists of a mass M hanging at the bottom end of a massless rod of length l, which has a frictionless pivot at its top end. A mass m, moving as shown in Fig. 42 with velocity v, impacts M and becomes embedded What is the smallest value of v suffi- cient to cause the pendulum (with embedded mass m) to swing clear over the top of its arc?
