A 6.03-g bullet is fired horizontally at a speed of 662 m/s directly toward a 3.89-kg wooden block. The wooden block is sliding on a frictionless surface and is moving toward the bullet at a speed of 2.68 m/s. The bullet passes through the block and the block's speed is reduced to 1.98 m/s. With what speed does the bullet emerge from the other side of the block?
