You have been asked to modify a spectacular pendulum that hangs so that it has a period of exactly 10 s. It consists of a 7.75 m long rod with a 0.25-m-diameter disk attached at the bottom (so that from the top end of the rod to the bottom end of the disk is 8.00 m). The rod and the disk have the same mass as each other. What’s it’s an original period? Do you need to make the rod shorter or longer to achieve your goal?
