(adsbygoogle = window.adsbygoogle || []).push({}); A mass on a spring, trying to find dispacement after at certain time. (Please Help!!)

1. The problem statement, all variables and given/known data

A 0.27 kg mass is suspended on a spring that stretches a distance of 4.9 cm. The mass is then pulled down an additional distance of 12.5 cm and released. What's the displacement from the equilibrium position with the mass attached (in cm) after 0.42 s? Take up to be positive and use g = 9.81 m/s^2

m=.27kg

t=.42s

g=9.81m/s^2

I don't know how to represent it, but I believe that 4.9 is the equilibrium.

12.5cm is the initial displacement (maybe x0?)

2. Relevant equations

I have no idea, this is what I need help with.

maybe u=1/2kx^2, but I don't have a k, and I don't need u, but it is the only spring equation I know

3. The attempt at a solution
