This time, the pendulum is 1.07 m long and has a mass of 4.92 kg. You give it a push away from vertical so that it starts swinging with a speed of 2.88 m/s. Due to friction at the pivot point, 1.00 Joule of the pendulum s initial kinetic energy is lost as heat during the upward swing. What maximum angle will it reach, with respect to the vertical, before falling back down? A 51.4 degrees B 52.8 degrees C 77.1 degrees D 65.0 degrees
