An object in simple harmonic motion has amplitude 3.2 cmcm and frequency 3.4 HzHz , and at tt = 0ss it passes through the equilibrium point moving to the right.
Part A
Write the function x(t) that describes the object's position.
x(t)=(3.2cm)cos((3.4ra(d)/(s))t)
x(t)=(3.2cm)cos((6.8\pi ra(d)/(s))t-(\pi )/(2)rad)
x(t)=(1.6cm)cos((6.8\pi ra(d)/(s))t)
x(t)=(3.2cm)cos((6.8\pi ra(d)/(s))t+(\pi )/(2)rad)
