A block weighing 96.6 lb is dropped from a height of 4 ft upon a spring whose modulus is 100 lb per in. What velocity will the block have at the instant the spring is deformed in 4 in.?

A solid gold bar is pulled up from the hold of the sunken RMS Titanic. (a) What happens to its volume as it goes from the pressure at the ship to the lower pressure at the ocean’s surface? (b) The pressure difference is proportional to the depth. How many times greater would the volume change have been had the ship been twice as deep? (c) The bulk modulus of lead is one-fourth that of gold. Find the ratio of the volume change of a solid lead bar to that of a gold bar of equal volume for the same pressure change.

A satellite similar to the Tethered Satellite in the figure below has a mass of 550 kg and is at the end of a 19.2 km long, 2.90 mm diameter cable with the tensile strength of steel.   (a)How much does the cable stretch (in m) if a 108 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 ✕ 109 N/m2.) 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 108 N force? J
