A bullet is fired horizontally and embeds itself in a block of wood as shown in the figure below. After the impact, the block and embedded bullet slide 12 mm and come to a stop. The mass of the bullet is 30 g, the mass of the wooden block is 10 kg, and the coefficient of kinetic friction between the block and the surface is μk = 0.4. a. Determine the velocity of the block and embedded bullet just after the impact. b. Determine the velocity of the bullet just before the impact.
