An object is undergoing simple harmonic motion along the x-axis. Its position is described as a function of time by x(t) = 2.8 cos(3.1t – 1.4), where x is in meters, the time, t, is in seconds, and the argument of the cosine is in radians. Find the amplitude of the simple harmonic motion in meters. What is the value of the angular velocity in radians per second. Determine the position of the object in meters and the objects velocity in meters per secondd when the time=0.
