A 2.50 g bullet, traveling at a speed of 460 m/s, strikes the wooden block of a ballistic pendulum, such as that in the figure below. The block has a mass of 270 g.

(a) Find the speed of the bullet/block combination immediately after the collision.

(b) How high does the combination rise above its initial position?

A bullet with mass m1 = 3.00 g is fired into a wooden block of mass m2 = 1.00 kg, that hangs like a pendulum. The bullet is embedded in the block (complete inelastic collision). The block (with the bullet embedded in it) goes h = 30.0 cm high after collision. Calculate the speed of the bullet before it hit the block.

In the figure, a bullet with mass m1 moving directly upward with speed v1i strikes and passes through the center of mass of a block with mass m2 which is initially at rest. The bullet emerges from the block moving directly upward and has slowed to a speed v1f. To what maximum height does the block then rise above its initial position?
