"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."
"find an expression for the bullet's speed vb. express your answer in terms of the variables m, m, k, d, and constant g."
i've been able to find a few solutions that produce the right result, but none that use the variable g, which masteringphysics is requiring. can anyone me find a correct equation for the problem that contains the g constant in it?
