Figure shows a displacement-versus-time graph of the periodic motion of a 3.8-kg mass on a spring. (a) Referring to the figure, do you expect the maximum speed of the mass to be greater than, less than, or equal to 0.50 m/s? Explain. (b) Calculate the maximum speed of the mass. (c) How much energy is stored in this system?
