Homework Help: Rotational kinematics?

  1. Nov 5, 2003 #1
    hello, i am new to this board. i was having some problems with this problem?

    at t = 0 a flywheel is rotating at 50 rpm. A motor gives it a constant acceleration of 0.5 rad/seconds(squared) until it reaches 100 rpm. The motor is then disconnected. How many revolutions are completed at t = 20 s ?

    thanks

    Welcome,

    This kind of post has to go in "homework help".

    In order to get help, you need to show something more than the bare problem.

    What have you tried?
    where are you stuck?
    what equations you expect to be useful?
    what happened when you tried them?
