**Simple harmonic motion [URGENT I have an exam tomorrow morning]**

## Homework Statement

Hi there. I don't know how to solve this problem about simple harmonic motion.

It says: A particle of 100 grams is animated with a simple harmonic motion, which starts 20cm from its equilibrium position, where it gets a speed of 200cm/s.

a) Calculate the period and the frequency of the oscillation.

## Homework Equations

[tex]x(t)=A\sin(wt)+B\cos(wt)[/tex]

## The Attempt at a Solution

Well, I have a problem with finding the angular frequency. I need the "K", the coefficient of the spring (its a way of thinking it as a mass attached to a spring). And I don't know how to find it.

Any ideas?

Bye there!
