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. "
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
