Simple Harmonic Motion: the Simple Harmonic Motion of an Object

Multiple Choice

Simple harmonic motion: The simple harmonic motion of an object is described by the graph shown in the figure. What is the equation for the position x(t) of the object as a function of time t?

A) x(t) = (4.0 cm) sin[(2π/8.0 s) t + π/3.0]
B) x(t) = (4.0 cm) cos[(2π/8.0 s) t + 2π/3.0]
C) x(t) = (4.0 cm) cos[(2π/8.0 s) t + π/3.0]
D) x(t) = (4.0 cm) cos[(2π/8.0 s) t - π/3.0]
E) x(t) = (8.0 cm) cos[(2π/8.0 s) t + π/3.0]
