A massless spring, with K=425 N/m, is hung vertically with the bottom end of the spring at position Y.i. A 3.50 kg mass is attached to the bottom of the spring and allowed to fall and oscillate.
A) How far below Y.i does the mass fall before coming momentarily to rest and reversing direction?
B) What is the amplitude of the oscillations?
C) What is the period of the oscillations?
