Question

6) The cannon on a battleship can fire a shell a maximum distance of 21.6 km.

(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 atmosphere—but 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 is 6.37 ✕ 10³ km. How many meters lower will its surface be 21.6 km from the ship along a horizontal line parallel to the surface at the ship?

_____ m
