1. A bullet of mass m=5 g moving with an initial velocity v_0, is shot into pendulum bob of mass M=25g. The pendulum bob is suspended by a light rod of length L=1.2 m.
What is the minimum velocity of the bullet so that the system after the collision barely swings through a complete vertical circle?
a) Assume an inelastic collision
b) Assume a perfect elastic collision
