Current Attempt in Progress Concept Simulation 10.3 illustrates the concepts pertinent to this problem. A 0.90-kg object is attached to one end of a spring, as in the first drawing, and the system is set into simple harmonic motion. The displacement x of the object as a function of time is shown in the second 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. Displacement +A 0 -A Amplitude = A- Pen Amplitude = A * = 0 m is the equilibrium position of the object. x (m) 0.080 2.0 40 0 10 3.0 Time (s) -0.080
