You have been asked to design a "ballistic spring system" to measure the speed of bullets. A bullet of mass m is fired into a block of mass M. The block, with the embedded bullet, then slides across a frictionless table and collides with a horizontal spring whose spring constant is k. The opposite end of the spring is anchored to a wall. The spring's maximum compression d is measured.What was the speed of a 2.1 g bullet if the block's mass is 1.5 kg and if the spring, with k = 40 N/m , was compressed by 15 cm ?
