An 0.50 kg object is attached to one end of a spring, and the system is set into simple harmonic motion. The displacement x of the object as a function of time is shown in the drawing below. With the aid of this data, determine the following values.
(a) amplitude A of the motion
(b) angular frequency
(c) spring constant k
(d) speed of the object at t = 1.0 s
(e) magnitude of the object's acceleration at t = 1.0 s
