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
One end of a string is secured to the ceiling of a classroom, and the other end of the string is attached to a sphere of mass 0.20 kg so that a pendulum is established. The sphere is raised at an angle of 15° above the sphere’s equilibrium position and then released from rest so that the pendulum oscillates, as shown in the figure. Location 1 is shown in the figure. A graph of the pendulum’s horizontal position as a function of time is shown in the graph (the graph is in the attached image). a. Calculate the value of the maximum kinetic energy of the sphere as it oscillates The sphere is raised to a new angle above the sphere’s equilibrium position that is less than the angle described for part (a). The sphere is released from rest so that the pendulum oscillates. b. Explain how the motion of the sphere changes, if at all, based on the appropriate evidence and/or reasoning.
