(1) A bullet of mass m and speed v passes completely through apendulum bob of mass M. The bullet emerges with a speed of v{2. Thependulum bob is suspended by a stiff rod of length l and negligiblemass. What is the minimum value of v such that the pendulum bobwill barely swing through a complete vertical circle? In otherwords, enough to cause the pendulum bob to reach the top of itscircular path.
