A uniform hollow disk with inner radius 30cm and outer radius 60cm has two pieces of thin wire wrapped around its outer rim and is supported from the ceiling. Suddenly one of the wires breaks and the remaining wire does not slip as the disk rolls down. Use conservation of energy to find the speed of the center of this disk after it has fallen a distance of 2m.

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
