A 14.3-g bullet is fired into a 5.21 kg block of wood. The block is attached to a spring that has a spring force constant of 450 N/m. The block and bullet continue to move, compressing the spring by 22.0 cm before the whole system momentarily comes to a stop. The coefficient of kinetic friction between block and the surface on which the block is resting is 0.35. Determine the initial speed of bullet.
