a bullet of mass 0.00105 kg and speed v passes completely through a pendulum bob of mass 85.1 kg. the bullet emerges with a speed v/2. the pendulum bob is suspended by a stiff rod of length 1.04 m and negligible mass. the acceleration of gravity is 9.8 m/s 2 . v v/2 m l what is the minimum value of v such that the pendulum bob will barely swing through a complete vertical circle? answer in units of m/s.
