Homework Statement



Homework Equations



The Attempt at a Solution



I just have a quick question about http://answers.yahoo.com/question/i...dDvWAH.7iY1ZZYRg--&paid=add_comment#openions"

When the answerer says that "For the general case (in case I made a numerical error), max amplitude is given by: A = g / (w^2)," is he just talking about this problem specifically or any problem in general?

It is only that problem specifically. The pebble will only remain on the board as long as the force acting on it is less than the force of gravity. If the maximum force, [tex]F=ma=m\omega^2 A[/tex] were greater than the force of gravity, then the pebble would be thrown off the board.

He stated the general case in terms of any angular frequency given, not for any problem in the world. That would be a bit silly. :p
