A 2.10-kg block is suspended from a springwith a spring constant of 380.0 N/m. A0.070-kg bullet is fired into the block from directlybelow with a speed of 160.0 m/s and is embedded inthe block.
Find the amplitude of the subsequent motion.
What fraction of the original kinetic energy of the bullet appearsas mechanical energy in the system of block-spring-bullet?
