Homework Help: When finding Angular Acceleration

  1. Mar 26, 2009 #1
    When finding Angular Acceleration, how is it that -7.129 x 10-4 rev/s2 equal to -4.47800 x 10-3 rad/sec2? In other words, how does the unit conversion work?

    There are 2*pi rad per rev because a revolution is once around a circle.
