1. A graph of position versus time for a mass oscillating in simple harmonic motion at the free end of a horizontal spring is shown below. Use the standard coordinate system (right/up is positive and left/down is negative). x (m) 1(s) D a. (0.5 pt) What is the amplitude of the oscillation? b. (0.5 pt) What is the period of oscillation? c. (0.5 pt) What is the frequency? d. (0.5 pt) At what points (A, B, C, D, and E) does the mass have the greatest speed? e. (0.5 pt) At what points (A, B, C, D, and E) does the mass have a positive velocity? f. (0.5 pt) At what points (A, B, C, D, and E) does the mass have a negative velocity? g. (0.5 pt) At what points (A, B, C, D, and E) does the mass have zero velocity? h. (0.5 pt) At what points (A, B, C, D, and E) does the mass have the greatest acceleration? i. (0.5 pt) At what points (A, B, C, D, and E) does the mass have the greatest kinetic energy? j. (0.5 pt) At what points (A, B, C, D, and E) does the mass have the greatest elastic potential energy
