he ballistic pendulum (see the figure below) is a device used to measure the speed of a fast-moving projectile such as a bullet. The bullet is fired into a large block of wood suspended from some light wires. The bullet is stopped by the block, and the entire system swings up to a height h. (a) Determine the ratio of the momentum immediately after the collision to the momentum immediately before the collision. Pf/Pi= (b) Show that the ratio of the kinetic energy immediately after the collision to the kinetic energy immediately before the collision is m1/(m1 + m2). Show your work.
