Problem 10.51
You have been asked to design a "ballistic spring system" to measure the speed of bullets. A spring
whose spring constant is k is suspended from the ceiling. A block of mass M hangs from the spring. A
bullet of mass m is fired vertically upward into the bottom of the block. The spring's maximum
compression d is measured.
