A 5.00-g bullet is fired horizontally into a 1.20-kg wooden block resting on a horizontal surface. The bullet remain embedded in the block, which is observed to slide 0.23 m along the surface before stopping. The coefficient of kinetic friction between the block and the surface is 0.20. What was the initial speed of the bullet before it enters the wooden block?
