Homework Help: Explanation of formula T = 2pi sqrt(m/k)

  1. Feb 26, 2016 #1
    1. The problem statement, all variables and given/known data
    This formula we've been using recently, I don't understand where it comes from.

    2. Relevant equations
    T = 2pi * sqrt(m/k)

    3. The attempt at a solution
    Hooke's law: F = -kx
    E(total) = .5mv^2 + .5kx^2
    Circumference of a Circle: C = 2 * pi * r

    I figure these piece together, but I don't understand how.

    You have to derive the equation for acceleration from a graphs of Shm. Look at them and try to get an equation for acceleration.
