A 5.87-g bullet is moving horizontally with a velocity of +348m/s, where the sign + indicates that it is moving to the right (seepart a of the drawing). The bullet is approaching two blocksresting on a horizontal frictionless surface. Air resistance isnegligible. The bullet passes completely through the first block(an inelastic collision) and embeds itself in the second one, asindicated in part b. Note that both blocks are moving after thecollision with the bullet. The mass of the first block is 1238 g,and its velocity is +0.631 m/s after the bullet passes through it.The mass of the second block is 1623 g. (a) What is the velocity ofthe second block after the bullet imbeds itself? (b) Find the ratioof the total kinetic energy after the collision to that before thecollision.
