**Gregory**, Sunday, January 30, 2011 at 10:11amPart one is asking for the speed of the pulse. The equation for speed is v = d/t (or v = s/t depending on your textbook. Velocity = Distance/Time. Since the pulse is traveling from the terminal to the other side, and back to origin, you must take double the distance of the rope. So you are looking at the equation: v = 1360m/15s (since 15s is how long it takes for the pulse to travel from and to the origin.) So the answer to the first part is 90.66 m/s. Part II im still working on, sorry.
