The ballistic pendulum was used to measure the speeds of bullets. It consists of a large block of wood of mass M = 5.4 kilogram, hanging from two long chords. A bullet of mass m = 9.5 gram is fired into the block, coming quickly to rest. The block + bullet then swing upward, their center of mass rising a vertical distance h = 6.3 centimeter before the pendulum comes momentarily to rest at the end of its arc. Find the speed of bullet just prior to collision?
