Question
Current Attempt in Progress
A 5.61-g bullet is moving horizontally with a velocity of +354 m/s, where the sign + indicates that it is moving
to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal
frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an
inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are
moving after the collision with the bullet. The mass of the first block is 1195 g, and its velocity is +0.709 m/s
after the bullet passes through it. The mass of the second block is 1639 g. (a) What is the velocity of the
second block after the bullet imbeds itself? (b) Find the ratio of the total kinetic energy after the collision to
that before the collision.
