A 7.45g bullet from a 9mm pistol has a velocity of 353m/s. It strikes the 0.725kg block of a ballistic pendulum and passes completely through the block. If the block rises through a distance h=12.1cm, what was the velocity of the bullet as it emerged from the block?

#### Solution Preview

Inelastic collision - bullet gets embedded into the pendulum block after collision and the combined mass moves as one.

Conservation of momentum still holds ...

#### Solution Summary

Conservation of momentum still holds well even for this inelastic collision. This solution includes explanation and calculations.
