1. A 10-g bullet moving horizontally strikes and passes through a 4.0-kg block moving with a speed of 4.2 m/s in the opposite direction on a horizontal, frictionless surface. If the block is brought to rest by the collision, and the bullet emerges with a speed of 320m/s, what is the initial speed of the bullet? (
