Simple Harmonic Motion and Reference Circle

  1. Feb 12, 2009 #1
    Thank you in advance!
    1. The problem statement, all variables and given/known data
    A 3.0-kg block is between two horizontal springs. Neither spring is trained when the block is at the position labeled x=0 m in the drawing. The block is then displaced a distance of 0.070m from the position where x=0m and is released from rest. (a) What is the speed of the block when it passes back through the x=0 position? (b) Determine the angular frequency w of this system.
    2. Relevant equations

    I have no idea.

    3. The attempt at a solution
    Help me!

    How does angular frequency relate to the frequency of cycles?

    7.54*10^4= 2pi*f
    12006*2.5s= 30016 times?
    It says to use three significant digits from start to finish. How do I do that? Sorry, I haven't learned this!
    Thanks danago!!
