Homework Help: Dynamics Problem: Incline Block and Moment of Interia

  1. Apr 5, 2015 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    ∑F=ma

    ∑M=Iα

    3. The attempt at a solution

    I used the dynamic equilibrium formulas to find the tension. The tension helps me to find the acceleration of the block. Then, I used kinematics to find the velocity. But, I'm not getting the right answer.


    correct answer: Vb= 0.5214 m/s 325°

    I do not see that you used the given moment of 0.3 Nm.
