(1 point) Afiexible cable suspended between two vertical supports is hanging under its own weight. The weight of a horizontal roadbed is distributed evenly along the x-axis with the density p : 1.1 lbfi't. The coordinate system is chosen so that the yaxis passes through the lowest point P1 and the os-axis is a : 3.5 ft below P1. lithe absolute value of tension force in the cable at point P1 is T = 1.5, then the initial value problem that governs the shape of the cable is (Use the notation dy/dm for the rst derivative) The solution of this problem is y : y(:v), where
