The cannon on a battleship can fire a shell a maximum distance of43.9km.

(a)Calculate the initial velocity of the shell in meters per second. (Enter the magnitude.) m/s

(b)What maximum height in meters does it reach? (At its highest, the shell is above a substantial part of the atmospherebut air resistance is not really negligible as assumed to make this problem easier. Assume the shell has been fired so as to maximize horizontal distance.) m

(c)The ocean is not flat, because the earth is curved. Assume that the radius of the Earth is6.3710³km. How many meters lower will its surface be43.9km from the ship along a horizontal line parallel to the surface at the ship? m

Does your answer imply that error introduced by the assumption of a flat Earth in projectile motion is significant here?
