A 250 g block of wood hangs from a light string 0.78 m long. The block is shot with a bullet of mass 4.2 g, which remains embedded on the block.

A) if the pendulum rises 5.5 cm above it's initial height, what was the initial velocity of the block with the embedded bullet?

B) what was the velocity of the bullet just before it hit the block?
