SUMMARY
The energy carried by a rope is directly proportional to the square of its amplitude. In this discussion, the initial amplitude is 15 mm, and the new amplitude is 20 mm. The factor by which the amplitude changes is calculated as the ratio of the new amplitude to the old amplitude, which is 20 mm / 15 mm. Consequently, the energy carried by the rope changes by a factor of (20/15)^2, resulting in an increase in energy by a factor of approximately 1.78.
