Damped Harmonic Oscillation Question
If a marble is placed on the end of a horizontal oscillating spring and the harmonic horizontal position of the marble as a function of time is given as :
If x = A ( 2 pi f t)
where A is amplitude
f is frequency
and t is time in seconds
If the spring oscillates every 0.5 seconds and has a maximum displacement of 0.2 m
what is the frequency?
what is the velocity as a function of time ?
how do you write the equation in the form given above for the position of the marble as a function of time ?
