bullet fired into wooden block (energy conservation)
Please help!A bullet of mass is fired horizontally with speed at a wooden block of mass resting on a frictionless table. The bullet hitsthe block and becomes completely embeddedwithin it. After thebullet has come to rest within the block, the block, with thebullet in it, is traveling at speed .1. Which of the following best describesthis collision?a. perfectly elasticb. partially inelasticc. perfectly inelastic2. Which of the following quantities, if any, areconserved during this collision?a. kinetic energy onlyb. momentum onlyc. kinetic energy and momentumd. neither momentum nor kinetic energy3. What is the speed of the block/bullet systemafter the collision?Express your answer in termsof , , and .
