Chapter 7, Problem 7.66(choose chapter or problem)
A ballistic pendulum can be used to measure the speed of a projectile, such as a bullet. The ballistic pendulum shown in Figure 7.12a 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.
