## Homework Statement

Ok, below is the question. I am having trouble with getting started. Like the first steps. A and B are the questions I am having trouble with.

*"A 1.00 kg glider attached to a spring with a force constant of 25.0 N/m oscillates on a frictionless, horizontal air track. At t = 0, the glider is passing through its equilibrium position with a velocity vx = - 0.150 m/s. (The negative sign means that the glider is headed in the direction which will compress the spring.)*

(a) Calculate the frequency and period of the glider’s motion.

(b) Calculate the amplitude of the simple harmonic motion. "

(a) Calculate the frequency and period of the glider’s motion.

(b) Calculate the amplitude of the simple harmonic motion. "

## Homework Equations

## The Attempt at a Solution

I just don't know how to get start with question A)

EDIT: This is from my notes

Frequency = 1/T

Where T = Period

Or Period = 1/f

Where f is Frequency

But I am not sure how to get the answer to A) for this question from that above data. ?

is this correct for period?

2*pi*sqrt( 1/25) = 1.25

so frequency would be 1 / 1.25 = .8?NOW, is this correct for B) amplitude:

KE = PE, so answer I got was when solving for x was: .03
