How are bungee cords measured?
Hereof, how do you measure the length of a bungee cord?
The unstretched length of the bungee cord is L = 0.52 m. When we hang Cosmo by the bungee cord, letting him come to rest, we find that the stretched length of the bungee cord is 1.25 m, an increase of x = 0.73 m (see figure below). We calculate the spring constant of the bungee cord: k = F/x = mg/x = 15.2 N/m.
One may also ask, how far can you stretch a bungee cord?
Bungee cord with a 100% elongation rating can be stretched to double its original length. For example a 12 inch length can be stretched to 24 inches. By comparison, a 12 inch length of bungee cord with a 50% elongation rating can only be stretched to 18 inches.
The first force that the bungee jumper experiences is gravity, which pulls down on everything and makes the jumper fall. The gravitational force is almost exactly constant throughout the jump. During the bungee jumper's fall, he or she also experiences a force due to air resistance.
