In an experiment designed to determine the velocity of a bullet fired by a certain gun, a wooden block of mass M = 530.0 g is supported only by its edges, and a bullet of mass m = 7.25 g is fired vertically upward into the block from close range below. After the bullet embeds itself in the block, the block and the bullet are measured to rise to a maximum height of 30.0 cm above the block's original position. What is the speed of the bullet just before impact? m/s
