Question

The Tethered Satellite in shown has a mass of 525 kg and is at the end of a 20.0 km long, 2.50 mm diameter cable with the tensile strength of steel.        (a) How much does the cable stretch if a 100 N force is exerted to pull the satellite in? (Assume the satellite and shuttle are at the same altitude
above the Earth.)                                                                                                (b) What is the effective force constant of the cable? 
(c) How much energy is stored in it when stretched by the 100 N force?
