Please show how you got the answers, not just the answers.

A 40.0 N force stretches a vertical spring 0.250 m.
(A) What mass must be suspended from the spring so that the system will oscillate with a period of 1.0 s?
(B) If the amplitude of the motion is 0.050 m and the period is as in part (a), where is the object and in what direction is it moving 0.35 s after it has passed the equilibrium position moving downwards?
(C) What force (magnitude and direction) does the spring exert on the object when it is 0.030 m below the equilibrium position, moving upward?
