A satellite similar to the Tethered Satellite in the figure below has a mass of 550 kg and is at the end of a 19.8 km long, 2.60 mm diameter cable with the tensile strength of steel. Tethered Satellite Bearth Return path>> through ionosphere (a) How much does the cable stretch (in m) if a 120 N force is exerted to pull the satellite in? (Assume the satellite and shuttle are at the same altitude above the Earth. Young's modulus for steel is 210 x 10 N/m.) 3.077514e?4 m (b) What is the effective force constant of the cable (in N/m)? N/m (c) How much energy (in J) is stored in it when stretched by the 120 N force?
