One end of a string is attached to an object of mass M; When the object is raised to a position X that is a height H above its lowest point and released from rest, the object undergoes simple harmonic motion. When the object passes through the equilibrium position Y it has a speed of v. Which of the following methods could a student use to determine the total mechanical energy at Position Y & why. Select 2 answers. A.ME = KE - PE because energy changes from KE to PE when the pendulum swings from X to Y B.ME = PE - KE because energy changes from PE to KE when the pendulum swings from Y to X C.ME = KE because this represents the maximum KE at Y as the system has 0 PE at Y D.ME = PE because this equation represents the maximum PE at X if the system has zero PE at Y

Definition Definition Special type of oscillation where the force of restoration is directly proportional to the displacement of the object from its mean or initial position. If an object is in motion such that the acceleration of the object is directly proportional to its displacement (which helps the moving object return to its resting position) then the object is said to undergo a simple harmonic motion. An object undergoing SHM always moves like a wave.
