A ballistic pendulum can be used to measure the speed of a projectile, such as a bullet. The ballistic pendulum shown in the figure consists of a stationary 2.50-kg block of wood suspended by a wire of negligible mass. A 0.0100-kg bullet is fired into the block, and the block (with the bullet in it) swings to a maximum height of 0.650 m above the initial position (see part b of the drawing). Find the speed with which the bullet is fired, assuming that air resistance is negligible.

Impulse, Momentum, and Collisions
EXAMPLE
In the figure, block 1 approaches a line of two stationary blocks with a velocity of v, =
10 m/s. It collides with block 2, which then collides with block 3, which has mass m, =
6.0 kg. After the second collision, block 2 is again stationary and block 3 has velocitý
= 5.0 m/s. Assume that the collisions are elastic. What are the masses of blocks 1
V3f
and 2? What is the final velocity v1f of block 1?
