The Simple Harmonic Motion of an Object Is Described by the Graph

question 16

Multiple Choice

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