P31 A hanging copper wire with diameter 1.4 mm (1.4x10^-3 m) is initially 0.95 m long. When a 36 kg mass is hung from it, the wire stretches an amount 1.83 mm, and when a 72 kg mass is hung from it, the wire stretches an amount 3.66 mm. A mole of copper has a mass of 63 g, and its density is 9 g/cm^3. Find the approximate value of the effective spring stiffness of the interatomic force.
