1D vertical spring A vertical spring with force constant 180 N/m is compressed by an attached 15 Kg block at rest. At 2.5 m above the 15 Kg block, a 10 Kg block is released from rest. The 10 Kg block falls 2.5 meters and collides with the 15 Kg block, and the collision is completed inelastic (the blocks stick together). The combined 25 Kg will move, compressing the spring more. Calculate how far down the 15 Kg block goes (the maximum magnitude of the downward displacement of the 15 Kg block from the initial position). Type your answer.
