a mass of 1.6 kg is hung from a vertical bungee cord that behaves as an ideal spring. the cord has an unstretched length of 0.50 m, and a circular cross section with diameter 1.1 cm. [5 10 points] the bungee cord stretches by 24 cm when the mass is added and slowly lowered to the equilibrium point. what is the cord’s spring constant? what is the young’s modulus e of bungee cord material? [10 10 points] next, the mass is then pulled an additional 4.5 cm below its equilibrium position and released. what are the magnitudes of the maximum velocity and maximum acceleration of the mass? if you didn’t find it in the first part, use 50 n/m for the spring constant.
