A commpon way of salvaging cannons from old wreacks is to attach an inflatable balloon filed with air. Assume that the cannon is a solid cylinder of iron which is 1.30m long with a radius 17.3cm. The density of iron is 7.87g/cm^3. a. What is the appartent weight of the cannon as it sits on the bottom in 10 meters of water in N? b. What minimum radius air bag is required to make the cannon neutrally bouyant? Assume that the air bag is spherical in shape and has negligable mass in cm. c. If the air bag were filled twice the volume necessary, what will be the tension in the rope between the air bag and the cannon when the air bag reaches the surface and comes to rest?
