The wave speed in a guitar string is 265 m/s. The length of the string is 63 cm. You pluck the center of the string with pulling it up and letting go. Pulses move in both directions and are reflected off the ends of the string.
1. When the pulses return, is the string above or below its resting location?
2. How long does it take for the pulse to move to the string end and return to the center?
3. If you plucked the string 15 cm from one end of the string, where would the two pulses meet?
