Calculating conservation of Energy, Frictionless Oscillatory Motion

  1. Jun 9, 2013 #1
    1. The problem statement, all variables and given/known data
    Use energy to show whether or not the data agrees with the law of conservation and explain.

    Mass-.3105kg spring constant-6.412 Equailibrium position-1.082
    Max positive postion (1) farthest distance to the right of the equlibrium position
    time-3.70s postion-1.303m Velocity-0.101m/s
    Min positive position (2) farthest distance to the left of the equilibrium postion
    time 4.40s postion .861m Velocity .061m/s
    Max Velocity (3) near the equilibrium positon
    time- 4.0s position-1.114m Velocity .981m/s


    2. Relevant equations
    http://en.wikipedia.org/wiki/Simple_harmonic_motion
    I am in algebra based physics and haven't gone over a lot of the variables that are used in these equations. But I used the simple harmonic equations I added the kenetic to the potential in the spring. then set it equal to the potential in spring multiplied by time.
    Ke+Pe=Pe(t3)

    3. The attempt at a solution
    .5mv2+.5kx2=.5kx2t3
    my numbers ended up being
    2.11=2.51
    is this correct?
