Cord Pole
How high above the floor will the object be when the cord breaks? (See below for details)?
A 25 kg object is being lifted by pulling on the ends of a 1.12 mm diameter nylon cord that goes over two 3.00 m high poles that are 4.4 m apart, as shown in the figure, http://session.masteringphysics.com/problemAsset/1058221/3/GIANCOLI.ch12.p79.jpg
How high above the floor will the object be when the cord breaks?
Nylon's tensile strength is 500*10^6 N/m^2
Unless you're measuring from the top of the object to the ground, there is no way to determine how far from the ground it is without knowing the height of the object.
The formula would be the height of the pole plus the thickness of the cord minus the distance between the top of the cord and the bottom of the object.
Since you don't know how tall the object is you can't complete the equation. The weight of the object and the distance of the poles makes no difference assuming the cord is strong enough to hold the weight and that the cord would break from being pulled apart.
Fishing pole broke so now it's an extension cord
