Rotational Kinematics Problem Interpretation

  1. Sep 15, 2009 #1
    1. The problem statement, all variables and given/known data
    If you step on your car's brakes hard, the wheels stop turning (i.e., the wheels "lock") after 2.0 revolution.

    Part A.
    At the same constant acceleration, how many revolutions do the wheels make before stopping if your initial speed is twice as high?

    2. Relevant equations
    Rotational Kinematics

    3. The attempt at a solution
    I need help interpreting the problem not doing it.

    Ok, the first part says it took 2 revolutions to startup.
    The actual question is asking me how many revolutions are made though. How are these two parts related?

    Figured it out. It's amazing how writing things out always puts it in perspective.
