A 5.37-g bullet is moving horizontally with a velocity of + 346 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 1179 g, and its velocity is + 0.556 m/s after the bullet passes through it. The mass of the second block is 1581 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.

- Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at vOi = 6.55 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of θ = 38.0° with the horizontal axis while the green disk makes an angle of ϕ = 52.0° with this axis as in Figure b.
