The displacement vs. time of a particle undergoing SHM is shown in the graph below. 12. In the graph, sketch in the displacement vs. time for in-phase SHM with exactly half the amplitude of the given SHM 15. In the graph above, sketch in the velocity of the mass vs. time, and label it "Vit\\" 14. In the graph above, sketch in the acceleration of the mass vs. time, and label it "Aft)." The kinetic energy vs. displacement of a 2 50-kg particle undergoing SHM on a mass-spring system is shown in the graph to the right. 80 60- Kinetic Energy ! 4.0- 20- Displacement xrem 15. What is the maximum speed of the mass
