Three different weights are suspended from three different springs. Each spring has an elasticity coefficient of 18.5. The equation for the vertical displacement is y= 1.5cosine(t times the square root of k/m), where t is time, k is the elasticity coefficient, and m is the mass of the weight. Find the period and frequency of the spring if the weight has a mass of .4 kilogram.

Thanks so much! My teacher never gave is that equation. She just told us to go home and try to learn the method.
