A wooden block is on a flat horizontal table. A bullet is fired horizontally over it, getting stuck in the block.
(a) Determine the speed of the bullet-block system immediately after the collision.
(b) What kind of collision is this?
(c) How far will the block travel until it stops? Consider that the bullet has 10g and the 10kg block. The initial speed of the bullet is 750 m/s, and the coefficient of kinetic friction between the block and the table is 0.3. Suppose further that the bullet does not make the block spin.
