And object is undergoing simple harmonic motion along the x-axis. Its position is described as a function of time by x(t) = 1.4 cos(3.5t – 1.4), where x is in meters, the time, t, is in seconds, and the argument of the cosine is in radians.
(a) What is the object’s velocity, in meters per second, at time t = 0?
(b) Calculate the object’s acceleration, in meters per second squared, at time t = 0.
