Concept Simulation 10.3 illustrates the concepts pertinent to this problem. An 0.80-kg object is attached to one end of a spring, as in Figure 10.6, 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. With the aid of these data, determine (a) the amplitude A of the motion, (b) the angular frequency w, (c) the spring constant k, (d) the speed of the object at t=1.0 s, and (e) the magnitude of the object’s acceleration at t=1.0 s.
