Ballistic pendulum

  1. May 7, 2008 #1
    The ballistic pendulum is a block with the mass 2.50kg suspended on a cable, the projectile has a mass of 0.010kg and is shouted with the initial velocity, after the collision the pendulum reach the height of h=0.65 m/s. Determine the initial velocity of the projectile.

    Hi uvburgos and welcome to PF,

    What are your thoughts on the question? Which concepts are involved? Have your read your class notes on the concepts involved?

    I do have the answer just need verify is my answer is correct (Vi=3.6m/s)

    No, I'm afraid your answer is incorrect.

    Reality check: Does 3.6 m/s seem like a realistic velocity for a bullet?

    I forget to write at the end to ignore the friction

    This doesn't change the answer. Your solution is still incorrect, conservation of energy does not apply here. You must you conservation of momentum.
