i. What will be the spring scale reading in newtons when the lead has been submerged to location 2?
ii. Does the spring scale reading increase, decrease, or stay the same when the cube is lowered from location
2 to location 3? Justify your answer by referencing the pressure of the fluid on the lead cube.
iii. The lead cube is lowered from above the oil's surface (location 1) to a spot just below the surface (location
2) until the cube is just above the bottom of the beaker (location 3). Describe any changes in pressure on
the bottom of the beaker during this process. Explain your answer.

m h 1. A crane released a block of mass 5.0 kg from a height of 2.0 m towards a spring with spring constant of 85 N/m as shown in the figure. Air resistance with a magnitude of 30.0 N acts on the block as it moves through the vertical height. (a) By how many meters was the spring compressed? (Ans.: 1.68 m) I (b) What is the velocity of the block just as it touches the spring? (Ans.: 3.90 m/s)
A scuba tank is dropped overboard and sinks to the ocean floor 20 ft below (T = 62 F). The composite metal (SG = 4.5) tank has a mass of 31.7 lbm when empty and has an internal volume of 0.355 ft3. The tank is currently filled with air to about 3000 psig. To retrieve the tank, you plan to dive down, open the valve, and let out air until the tank begins to float upward. Then, I realized that my plan to float the tank by letting out air wouldn't work. My second thought is to swim down, attach an empty plastic bag to the air valve, and release air from the tank into it. Will this work? If so what will be the volume of air in the bag when the tank just lifts off the ocean floor (ft3) and what will be the mass of air in the bag?
sailing vessels can carry lead ballast such as bricks to keep the vessel properly oriented and upright in the water. Consider a vessel that takes on cargo and the crew jettisons a total of 0.500m^3 of the lead ballast into water 2000 m deep. Seawater's density is equal to 1.025g/cc while lead's bulk modulus equals to 42 GPa. Find the change in the volume of the lead at 2km depth.
