Answer 1

t the lowest point of its swing, a pendulum has maximum kinetic energy and minimum potential energy. According to the principle of conservation of mechanical energy, the total mechanical energy in a closed system remains constant if only conservative forces are acting.In this case, the total mechanical energy of the pendulum is given as 500 J. At the lowest point, all of this energy is converted into kinetic energy because the potential energy is at its minimum (assuming it is zero at the lowest point).Therefore, the kinetic energy of the pendulum at the lowest point is 500 J.
