A weight stretches one spring 3 in. and a second weight stretches another spring 9 in. If both weights are simultaneously pulled down 1 in. below their respective equilibrium positions and then released, find the first time after t = 0 when their velocities are equal.

Are the two weights the same? Are the two springs the same? I don't think the problem can be solved without further information.
