the displacement of a simple harmonic oscillator versus time is
described by the function x = Asin(wt + phi)
find the speed when the displacement is sqrt(3) A/2
the answer is piA/2 but I have no idea how the professor got it...
the function for the velocity at point x in our book is
v_x_ = -wAsin(wt + phi)
for some reason it is hard for me to associate the position x with the speed... is there a formula that gives the velocity by just plugging in x?
I just also found a diagram that gives T = 2s which I didn't see before
