Circular Momentum

  1. Jan 30, 2008 #1
    1. The problem statement, all variables and given/known data
    At t1 = 1 s, the acceleration of a particle moving at constant speed in counterclockwise circular motion is [​IMG]
    At t2 = 3 s (less than one period later), the acceleration is [​IMG]
    The period is more than 2 s. What is the radius of the circle?
    2. Relevant equations

    3. The attempt at a solution
    I figured out the period is 2.67 seconds and the acceleration is 7.21 m/s^2. Then I get stuck
