Question

NOTE: Answer seen in Part B of screenshot is incorrect as given to me by previous expert. Could I please be given the correct solution?

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. Part A Find an expression for the bullet's speed up.
