The cannon on a battleship can fire a shell a maximum distance of 32.0 km. (a) calculate the initial velocity of the shell. (b) what maximum height does it reach? (at its highest, the shell is above 60% of the atmosphere—but air resistance is not really negligible as assumed to make this problem easier.) (c) the ocean is not flat, because the earth is curved. assume that the radius of the earth is 6.37×103 km. how many meters lower will its surface be 32.0 km from the ship along a horizontal line parallel to the surface at the ship? does your answer imply that error introduced by the assumption of a flat earth in projectile motion is significant here?

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
