If a diver of mass m stands at the end of a diving board with length L and linear density , then the board takes on the shape of a curve y = f(x), where and E and are positive constants that depend on the material of the board and g (< 0)is="" the="" acceleration="" due="" to="" gravity.="">
(a) Find an expression for the shape of the curve.
(b) Use f (L) to estimate the distance below the horizontal at the end of the board.
