- In my homework, I am asked to derive an equation for V0. The homework question is as follows: A howitzer fires a shell with a velocity of v0 at an angle Θ above the horizontal. The howitzer is on a plateau and the shell lands down in the plain below, a vertical distance d below the plateau and a horizontal distance L from where the howitzer is. Derive an expression for the magnitude of the initial velocity, V0, as a function of d, L, g, and Θ. Any help would be appreciated as I have worked on this problem for quite a while and I am not making progress.Vector A has a magnitude of 15.0 units and it points in a direction 310° counterclockwise from the positive x-axis.
