Mechanics velocity of disc question

  1. Apr 2, 2013 #1
    1. The problem statement, all variables and given/known data
    The disc rolls without sliding on the curved surface. What is the velocity of point A attached to the disc?
    Ans: 1.69 m/s, directed at 45o upwards.


    2. Relevant equations
    v=ωR


    3. The attempt at a solution
    v=ωR = 10rad/s * 40mm

    hi themster! :wink:

    use vector addition for the relative velocities (disc-arm and arm-earth) …

    show us what you get :smile:
