9. 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 ra-
dius of the Earth is 6.37 * 109. 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?
