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 0.2 kg. The sphere is raised at an angle of 15o 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. Calculate the maximum kinetic energy of the sphere as it oscillates.
