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.
A: Find an expression for the bullet's speed vB.
B: What was the speed of a 13g bullet if the block's mass is 2.5kg and if the spring, with k = 60N/m , was compressed by 45cm ?
