bullet of mass 10 8 is shot up a vertical pipe. The top of the pipe is covered by a 2.0 kg block. The bullet strikes the block at a speed of 500 m/s and embeds itself in a block. As a result: (A) (2 pts) The collision is (circle one): (i) elastic, (ii) inelastic, (ii) perfectly inelastic (B) (8 pts) What percentage of the initial kinetic energy of the bullet is dissipated in the collision? Percentage = (C) (4 pts) If the collision lasted 0.005 s, what is the magnitude of the average force the bullet exerted on the block during the collision? Avg. force = (D) (4 pts) To what maximum height does the block rise above its initial position? You may draw an energy bar chart to answer this question. Max height =
