In kick boxing, it is found that the force, f, needed to break a board, varies inversely with the length, l, of the board. If it takes 4 N of force to break a board 3 feet long, how many Newtons of force will it take to break a board that is 7 feet long?
l = 1.33
l= 1.714
If Q = 4 when W = 6, and Q varies directly as W, find Q when W = 9.
