A wooden plank is placed over a pit that is 5.00 m wide. A student stands in the middle of the plank and begins jumping upand down such that she jumps two times each second. The plankoscillates with a large amplitude, with maximum amplitude at itscenter.
A. What is the speed of the travsverse waves on the plank?
B. At what rate does the student have to jump to producelarge-amplified oscillations if she stands 1.25 m from the edge ofthe pit.
