A bullet of mass 5.0 g is fired horizontallyinto a 2.3 kg wooden block at rest on a horizontal surface. The coefficient of kinetic friction between block andsurface is 0.26. The bullet comes to rest in the block, which moves2.30 m.
(a) What is the speed of the block immediately after the bulletcomes to rest within it?
(b) At what speed is the bullet fired?
