question 9

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]
