A 0.90-kg block is suspended from a spring with a spring constant of 640.0 N/m. A 0.030-kg bullet is fired into the block from directly below with a speed of 270.0 m/s and is embedded in the block.
a) Find the amplitude of the subsequent motion.
b) What fraction of the original kinetic energy of the bullet appears as mechanical energy in the system of block-spring-bullet?
