A 5.5 gram bullet is fired into a block of wood with a mass of 22.6 grams. The wood block is initially at rest on a 1.5 meter tall post. After the collision the wood block and the bullet land 2.5 meters away from the base of the post. Find the initial speed of the bullet.
(After collision the bullet and the wood become one object) (The initial velocity is the velocity of the bullet when it strikes the wood)
