A massless Hooke's Law spring has unstretched length of 1.750 m. When a 37.5 kg mass is placed on it, and slowly lowered until the mass is at rest, the spring is squeezed to a length of 1.712 m. A mass of 95.2 kg is dropped on the spring from a height of 3.75 m. Use energy methods.

Force constant mainly means spring constant in physics, which ultimately refers to Hooke's law Hooke's law is a principle of physics that states that the force (F) needed to extend or compress a spring by some distance X is proportional to that distance. That is: F = kX, where k is a constant factor

Dec 10, 2006 I never said anything about the mass of the spring. I thought you were asking about how to measure the spring constant of a (presumably massless) spring by hanging a mass off one end. If the spring constant is high enough (in other words, if the spring is stiff enough) you can neglect the mass of the spring in measuring its spring constant.
