Homework Help: Simple Harmonic Motion

  1. Dec 7, 2009 #1
    If you couldnt tell im new to the board so any tips would be appreciated :)
    edit once again, im sorry for not showing work but i really dont understand it, when i do the work i just kinda wing it and throw stuff together
    1. The problem statement, all variables and given/known data

    As shown a 0.5 kg mass is attached to a spring. The mass is
    initially pulled to the right to amplitude xm and released from
    rest. At t = 2.6 seconds the following info is recorded. x = -
    0.15 m , and the force on the mass is = +1. 2 N.

    c) determine the amplitude ā€œxm ā€
    d) Determine the velocity at t = 2. 6 seconds and the direction of this velocity vector.
    e) Determine the period ā€œPā€ of the mass.
    f) Find the spring constant K
    g) Determine the total energy of the mass at t = 10 seconds

    2. Relevant equations
    This is where im having trouble,

    3. The attempt at a solution
    I have tried numerous times and checked numerous websites to no avail. I am simply just trying to understand this concept and it is way beyond me. I would just like to know how to do it rather then just getting an answer please. I have tried a bunch of different ways and havent even came close to the right answer. I really apreciate your help
