**drwls**, Wednesday, August 8, 2012 at 12:06pmSpring constant is inversely proportional to spring length. The original spring constant k becomes two springs with constants k1 = 3k and k2 = 3k/2, in parallel.

The effective spring constant of springs in parallel is obtaned by adding the separate spring constants; so the new spring constant becomes

k' = k1 + k2 = 9k/2.

The new period of oscillation is:

P = 2*pi*sqrt(m/k')

= 2*pi*sqrt(2/9)*sqrt(m/k)

= (2/3)*pi*sqrt(2m/k)
