Homework Help: Angular position, speed, and acceleration

  1. Apr 24, 2009 #1
    1. The problem statement, all variables and given/known data
    A dentist's drill starts from rest. After 3.30 s of constant angular acceleration, it turns at a rate of 2.52 multiplied by 104 rev/min.

    Find the drill's angular acceleration.

    Determine the angle through which the drill rotates during this period

    2. Relevant equations
    3. The attempt at a solution


    I know the answers are in the wrong units so can someone tell me what to do change my rev/min into rad/s2 for the first part and to find rad for the second part?
