The cannon on a battleship can fire a shell a maximum distance of 39.0 km. (a) Calculate the initial velocity of the shell. m/s (b) What maximum height does it reach? (At its highest, the shell is above a substantial part of the atmosphere--but air resistance is not really negligible as assumed to make this problem easier.) m (c) The ocean is not flat, since the earth is curved. How many meters lower will its surface be 39.0 km from the ship along a horizontal line parallel to the surface at the ship? mDoes your answer imply that error introduced by the assumption of a flat earth in projectile motion is significant here? (Select all that apply.) O The error is insignificant compared to the size of a target. O The error is significant compared to the distance of travel. O The error could be significant compared to the size of a target. O The error is insignificant compared to the distance of travel.
