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. (C) If the initial horizontal component of the balls velocity is 90.0 m/s and its initial angle is 0-24 degrees, does the cannonball clear the wall? If not, how high above the ground is the ball when it hits the wall?

Cannon problem: There is a new cannon entering service. The artillery crews need some information about the cannon's behavior so they can make adjustments to the firing angle as needed. When the engineers tell the artillery crew the range to the target, the crew must be able to calculate and set the proper firing angle for the cannon quickly. a) In order to calculate the proper firing angle what do they need to know about the cannonball leaving the cannon? (Ignore the height of the cannon above the ground. For now we will assume it makes little difference) b) Given your answer for part a, we need to identify the point in the cannonball's flight when it has its "initial velocity". The cannonball is clearly moving inside the barrel of the cannon, but at which point in the cannonball's path do we mark the initial velocity? The cannonball is packed onto a mass of gunpowder in the base of the cannon. When the powder is ignited, the chemical reaction produces gas and a large amount of heat…

A tennis ball rolls off the edge of a tabletop 0.750 mm above the floor and strikes the floor at a point 1.60 mm horizontally from the edge of the table. A) Find the time of flight of the ball.   B) Find the magnitude of the initial velocity of the ball.   C) Find the magnitude of the velocity of the ball just before it strikes the floor.   D) Find the direction of the velocity of the ball just before it strikes the floor.

7. A bullet is fired downward at an angle of 30° below the horizontal. 3.20 seconds later, the bullet hits a target that is 120 m horizontally to the right of the starting point. Let x direction be to the right and y direction point upward. a) Find vox, the x-component of the initial velocity of the bullet. b) Find the y-component of the initial velocity of the bullet. Voy,
