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?© BrainMass Inc. brainmass.com March 4, 2021, 6:07 pm ad1c9bdddf
Inelastic collision - bullet gets embedded into the pendulum block after collision and the combined mass moves as one.
Conservation of momentum still holds ...
Conservation of momentum still holds well even for this inelastic collision. This solution includes explanation and calculations.
