1. A clock keeps time by utilize of a simple pendulum. The pendulum has a mass of 0.5 kg suspended 26 cm below the pivot point; however the clock is running slow. What adjustment could you make to make the clock run at the proper rate?
2. A violin string is stretched between the bridge and the tuning peg. When the string is pulled to the side a distance d (such as when you are about to pluck it) the string opposes the pull by a force of magnitude F = Kd (where K is a constant) in the opposite direction that the string is pulled (i.e. it is a restoring force). When the string is released will it execute simple harmonic motion? How do you know? If you are not certain then reread the section 14.2 of the text.
