A cannon ball is fired with an initial velocity vo at a wall that is 100. meters tall and located 450. meters away. The initial angle of launch of the cannon ball is 0. We want to determine if the cannon ball will clear the wall. If not how high-up will the ball strike the wall from the ground. (A) Sketch a graph showing position of the cannonball during its flight (y versus x) showing and labeling the initial velocity vector. Identify and write knowns and unknowns (B) Without using numerical values, determine which physics equations of motion will help solve this problem. Simplify as useful for this particular case.
