Linear acceleration

  1. Dec 1, 2008 #1
    1. The problem statement, all variables and given/known data
    Determine the linear acceleration of the tip of the rod. Assume that the force of gravity acts at the center of mass of the rod, as shown

    2. Relevant equations
    So there is a first part to this problem that i already got
    A uniform rod of mass M = 5.02kg and length L = 1.08m can pivot freely (i.e., we ignore friction) about a hinge attached to a wall, as seen in the figure below.The rod is held horizontally and then released. At the moment of release, determine the angular acceleration of the rod. Use units of rad/s^2. So i got the right answer for this and it was 13.6 rad/s^2. i just dont know what to do for the second part

    3. The attempt at a solution

    Linear acceleration is related to angular acceleration by the eqn. r(\alpha) = a
