The following is a standard question found in many textbooks:
Question: You are at a furniture store and notice that a Grandfather clock has its time regulated by a physical pendulum that consists of a rod with a moveable weight on it. When the weight is moved downward, the pendulum slows down; when it is moved upward, the pendulum swings faster. If the rod has a mass of 1.23 kg and a length of 1.25 m and the weight has a mass of 1.81 kg where the mass should be placed to give the pendulum a period of 2.00 seconds?
I need help to solve the above question and measure the distance in meters from the top of the pendulum. Thanks.
