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

A 4.00 g bullet is moving horizontally with a velocity of +355 m/s as shown in figure below. The bullet is approaching two blocks resting on a horizontal frictionless surface. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as shown in part (b). Note that both blocks are moving after the collision with the bullet. The mass of the first block is 1150 g and its velocity is +0.550 m/s...
