You hang a heavy ball with a mass of 14 kg from a gold wire 2.5 m long that is 2 mm in diameter. You measure the stretch

of the wire, and find that the wire stretched 0.00139 m.

(a) Calculate Young's modulus for the wire.

(b) The atomic mass of gold is 197 g/mole, and the density of gold is . Calculate the interatomic spring

stiffness for gold.
