Secundaria Spring Constant

[Atlantic717]

The left side of the figure shows a light (`massless') spring of length 0.330 m in its relaxed position. It is compressed to 78.0 percent of its relaxed length, and a mass M= 0.130 kg is placed on top and released from rest (shown on the right).

The mass then travels vertically and it takes 1.50 s for the mass to reach the top of its trajectory. Calculate the spring constant, in N/m. (Use g=9.81 m/s2). Assume that the time required for the spring to reach its full extension is negligible.

Esto no va aqui...

y es un ejercico exactamente igual a este ( con los datos cambiados ):
