1) Observe the following three graphs that describe the motion of different objects, all of them subjected to springs of the same elastic constant. The time indicated by the vertical dashed line is the same and you can call it with the letter T. The scale of the displacement x= x(t) is indicated in terms of the letter A, which is the maximum displacement of the first object. zfi a) Write the mathematical equation for the motion of object I, in terms ofA and T. b) Express the period of the motions of objects II and ill in terms of T. 0) Write the equations of motion of II and III in terms of A and T. _ d) Assume that object I has mass M. First express the mass of an oscillating object in terms of the natural frequency of the oscillations. Then, express the mass of objects II and III in terms of the mass of Object l. e) State the total energy of oscillation of each object, in terms of its mass, amplitude, and period. Compare the energy of objects II and III with the energy of the first object
