A bullet of mass m30 g or 03 kg is fired into a wooden, Ask an Expert

Academics

A bullet of mass m=30 g or .03 kg, is fired into a wooden block of mass M=5.0 kg. The block is attached to a string of length 1.5 m. The bullet is embedded in the block, causing the block to then swing. If the block reaches a maximum height of h=.30m, what was the initial speed of the bullet?
