Homework Help: physics

Posted by sand on Tuesday, December 27, 2011 at 6:03am.

A large, cylindrically-shaped weight is suspended from a long spring found hanging from a rafter. The weight is slender metal cylinder about two meters long that is suspended with its flat bottom about half meter above the level concrete floor. When a 1 kg mass is added, the large weight sank down an additional 3 mm. Then, after removing the mass, the larger weight is slowly made to oscillate up and down with a frequency of twelve oscillations per minute.
What is the force constant of the spring?
What is the mass of the unknown weight?
If the weight is pushed down 10cm and released, how fast is it moving at its maximum speed?
