(spring problem) please help!!!!!!!!!!

Having some trouble with this. Would appreciate your help please.

An object weighing 128 pounds is suspended from a spring, streching the spring 2 feet beyond its natural length. The object is then released from rest at a point 6 inches above the equilibrium position.

a. Find a function which describes the position of the object at any time t.
b. What is the position of the object at time t= pi/12 sec? be precise
c. Is the object moving upward or downward at this time? Explain

Welcome to PF.

What have you done so far? What kind of motion do you think you are dealing with?

What do you mean by motion

What do you mean by motion
Well you have a block on a spring and you raised it 6 inches from its rest position, I'd think when it gets released it's going to do something.

I understand that, but how do I Find the function which describes the position of the object at any time t.

Well you need to know how its going to move to know that.

What will happen when you release it from the raised position?

Hint: The way they give the time in the second question is a huge clue to the type of motion.

Do you know how to do it?
Please let me know

Sorry it doesnt work like that, we dont just give answers out.

You have to have shown that you've made some effort to answer the question on your own.
We've even told you where to start.

yeah i know, i just need some more hint to do this problem. Please help

What do springs do? If you could choose 1 word to decribe it.

it's hard to give any more hints as then it would basically be telling you the answer. infact you could probably check wikipedia and get the answer stright away.
