Homework Help: Finding resultant velocity from angular acceleration

  1. Mar 4, 2015 #1
    1. The problem statement, all variables and given/known data
    Michael starts spinning the rope at a rate of 2.00 rad/s^2 while he starts running towards the target at 4.00m/s^2. This distance betweens Michael's elbow and the end of the rope form a straight 1.2m segment. If Michael takes 3 seconds before he launches the rope at the target, what is the resultant velocity of the rope when it leaves Michael's hand.

    2. Relevant equations
    at= (v2-v1)/2 (i think)
    at=ra (at= linear acceleration, a = angular acceleration)

    3. The attempt at a solution
    I believe to solve I would have to convert angular acceleration to angular velocity but I cannot figure out how to do that. Any help clarifying or a diagram would be huge. Thank you for reading

    What is the relation between angular acceleration and angular velocity? What is the relation between angular velocity and velocity?

    You probably have some kinematic equations that can handle that "transformation".
