Acceleration of block B on top of wedge A on a ramp

  1. Feb 23, 2013 #1
    1. The problem statement, all variables and given/known data
    A 12-lb block B rests on the upper surface of a 30-lb wedge A on a 30° ramp. Neglecting friction, determine immediately after the system is released from frest (a) the acceleration of A, (b) the acceleration of B relative to A.

    2. Relevant equations

    ƩFx=mA aA
    aB = aA + aB/A
    3. The attempt at a solution
