Angular Velocity and Acceleration

  1. Dec 11, 2011 #1
    1. The problem statement, all variables and given/known data
    Link AB has angular velocity and angular acceleration as shown. Determine the velocity and
    acceleration of point C and the angular acceleration of link BC at this instant. Express them as
    Cartesian vectors.

    2. Relevant equations

    vA = 0
    aA = 0
    w= -2k
    (alpha) =2k
    3. The attempt at a solution
    I have found that the point b has a velocity of -j

    Im not sure how to equate this to the angular velocity of BC or the angular acceleration of BC.

    I have used tried applying the ac = (alpha) x rc/b - w2rc/b

    but this isnt producing any solution
