Say I push down on a very large drum head that lies in the z = 0 plane at equilibrium. Suppose there is no friction between my finger and the drum head. Suppose my finger tip pushes thedrum head down some distance d. Suppose I accelerate my finger tip tosome constant velocity v in the x direction while always keeping myfinger tip in the plane z = -d.Are waves produced during the acceleration of my finger?Once my finger is in motion does it tend to stay in constant motion,that is does the drum head resist acceleration or deceleration of myfinger tip?
