The Cannon on a battleship can fire a shell a maximum distance of 45.0 km
(A)Calculate the initial velocity of the shell.
Answer 664.42 m/s
(B)what maximum height does it reach? (At its height, the shell is above a substantial part of the atmosphere--but air restance is not really negligible as assumed to make this problem easier)
Answer 11300 m
(C)
The ocean is not flat, since the earth is curved. How many meters lower will it surface be 45 km from the ship along a horizontal line parallel to the surface at the ship?
Answer ? M
