A 1 lb weight is suspended from a spring. Let y give the deﬂection (in inches) of the weight from its static deﬂection position, where “up” is the positive direction for y. If the static deﬂection is 24 in, ﬁnd a differential equation for y. Solve your equation and determine the period and frequency of the simple harmonic motion of the weight if it is set in motion. I'm having a hard time starting, I don't know how to set up the differential equation. I assume that an initial position will be y(24) = 1, but I can't get past the initial assumptions. Anything to help? Thanks!
