Homework Help: Andgular Displacement, and speed

  1. May 2, 2009 #1
    1. A fisherman is dozing when a fish takes the line and pulls it with a tension T. The spool of the fishing reel is at rest initially and rotates without friction (since the fisherman left the drag off) as the fish pulls for a time t. If the radius of the spool is R, and its moment of inertia is I, find
    a. The angular displacement of the spool
    b. The length of the line pulled from the spool
    c. The final angular speed of the spool

    I know that angular displacement is equal to theta = theta final minus theta initial, but i dont know how to relate it to this question. Any help would be greatly appreciated.
