A bug on the surface of a pond is observed to move up and down a total vertical distance of 7.0 cm, from the lowest to the highest point, as a wave passes.
Part A
If the ripples decrease to 4.0 cm, by what factor does the bug's maximum KE change?
Express your answer numerically.
\frac{KE_{max \text{ 4.0 cm}}}{KE_{max \text{ 7.0 cm}}} =
