Question

This question refers to the Post Pendulum exercise we did in Laboratory(see Figure below). Suppose the pendulum is 108 cm long, and it swings from a hook that is 110 cm above the table. A thin horizontal rod is placed 18.0 cm above the table so that it will cause the pendulum string to hit it and wrap around it when the pendulum reaches it lowest point. The pendulum ball has a mass of 120 g. Assume the rod is of negligible thickness, the radius of the cirde that the pendulum will move in after it hits the rod will be x cm. If the pendulum ball completes the circle, the highest point in its circular path will be x cm above the table. The minimum height from which the pendulum ball will complete the circle is x 34.0cm ; ﹀ 50.0cm x42.0 cm
