The displacement vs. time of a particle undergoing SHM is shown in the graph to the night. 19. In the graph, sketch in the displacement vs. time for in-phase SHIM with exactly half the amplitude of the given SHM 20. In the graph above, sketch in the displacement vs. time for SHIM that is exactly 7/ 6 out of phase. 21 How many degrees is this phase ang :? How many radians." In red. In purple Or you can shift is to the right. One period - T- 9501 360 /6 - 60. One period . 7. 2arad. 2mrad/6
