Two cannonballs are fired horizontally at a velocity v. One is fired from a height of h, and one 3h. a) State an expression for the ratio of the displacement of the cannonball fired at 3h to the displacement of the one fired at h before either hits the ground. b) State an expression, in terms of v and h, for the ratio of the displacement from the firing point to the landing point of the cannonball fired at 3h to the one fired at h. (The displacement is the total displacement in both vertical and horizontal)
