While finding the displacement is important, it is also necessary to be able to find the velocity of a simple harmonic
oscillator as a specific point in time.
Velocity is related to displacement in the sense that it is its derivative (the slope of a displacement vs. time graph's
tangent line at a particular time).
** Overlooking rather tedius and unimportant derivations **
v(t) = -Aωcos(ωt)
Where: v(t) = the velocity at time, t (s)
A = the maximum displacement (m)
ω = angular acceleration = 2πf = 2π/T (rad/s)
