Problem 13 A 75 gram bullet is fired into a 1.5 kg block, which is initially at rest on a flat surface. The bullet becomes embedded in the block, and the block slides 25 meters before coming to a stop. The coefficient of kinetic friction between the block and the surface is 0.25. What was the speed of the bullet just before striking the block?
