Homework Statement
A massless spring of length 0.270 m is in its relaxed position (left diagram). It is compressed to 71.0 percent of its relaxed length, and a mass M = 0.140 kg is placed on top and released from rest (shown on the right). The mass then travels vertically, taking 1.20 s to reach the top of its trajectory. Calculate the spring constant

Homework Equations
The Attempt at a Solution
I tried using conservation of energy, but kept getting stuck not being able to find how high it goes or the velocity when it leaves the spring
