ball is fired from a cannon inclined at 360 above the horizontal. The speed with which it leaves the barrel is 200 m/s and the mouth of the cannon is 2 m above ground level. Assume level ground. a) what are the horizontal and vertical components of the initial velocity of the cannon ball ? b) Determine the velocity of the cannon ball at t = 6 seconds. c) How far down range does the ball land

a guy is throwing pumpkins off a five story (15 meters high) building and wants the messiest result possible (highest velocity impact). a) he first throws a pumpkin downward at 45 degrees below the horizon at 15 m/s. how fast does the pumpkin hit the ground? at what angle does it hit? b) he then throws a second pumpkin upward with the same velocity 45 degrees above the horizon. how fast does the second pumpkin hit the ground? c) which strategy (throwing the pumpkin up or down) results in a higher velocity impact? think about why this might be

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…

Во Font Arial Bold B 2. In a basketball game, a player shoots the ball at a velocity of 4.31 m/s at 17.30 above the horizontal. A player on the other team jumps up and blocks the ball at the maximum height. A) Character How far horizontally does the ball travel to where it is blocked? B) How long is the ball in the air before being blocked C) If the ball wasn't blocked, what is the magnitude and direction of the velocity when the ball returns to the launch height?
