What is the total momentum of cannon and shell before and after firing?
Before the cannon is fired, the momentum is zero. So, after firing, the momentum must still be zero. The momentum of the shell is equal and opposite to that of the cannon, because there is an action and an equal reaction force. Since the momentum difference must be equal: (mv)cannon = (mv)shell Thus, (mv)c - (mv)s = 0 A simple way of looking at it is this is: If the shell is 100 times lighter than the cannon then the shell will move off 100 times faster than the cannon recoils. Remember that, in explosions, the lighter portion moves off faster than the heavier one.
What does it mean when you see a pole protruding from the cannon barrel?
There are 3 times that a pole would be in a cannon barrel:First to swab the cannon barrel of debris from previous firing,To ram down the cartridge,Finally to ram down the cannonball.
Why is the speed of a cannonball greater when shot from a cannon with a longer barrel?
The energy needed to move a cannonball is created by burning fuel--usually gunpowder but nothing says they couldn't make a cannon that burned propane to fire projectiles. Anyway, if you're firing a round the speed of that cannonball is determined in part by how long the energy's being applied to it. The longer the barrel is, the longer the energy will be applied and the faster the cannonball will go.
Were Huck's friends firing a cannon on the ferryboat?
They were hoping the firing of the cannon would bring Huck's body to the surface of the river.

What is a breech of a cannon?
the cannon breach is where the artillery shell is inserted for firing...................
What is the maximum height a sphere shot from cannon can reach?
That depends on basically three things: the angle at which the cannon is fired, the velocity of the projectile, and the acceleration of gravity. The maximum range of the cannon is achieved with a firing angle of 45 degrees to the horizontal. But the maximum height is achieved when the firing angle is 90 degrees to the horizontal, that is, when the cannon is pointing straight up into the air. (Which can be very dangerous to the artillery personnel firing the guns!) So, if we assume that the cannon is on Earth, not some other planet, and fired straight up into the air, can we determine how high the cannonball will go? Yes, if we know the velocity of the cannonball as it leaves the end of the cannon's tube. Once the cannonball leaves the end of the tube, it begins to slow down because of the acceleration of gravity. We can use the energy equations to calculate the maximum height of the cannonball. We know that kinetic energy is defined by the equation Ek = mv2/2. We also know that potential energy (due to altitude) is defined by the equation Ep = mgh. Equating the two, we get mv2/2 = mgh. Rearranging the terms to solve for h, we get: h = v2/2g. (Note that g = 9.8 m/s2 = 32.2 ft/s2.) So, let's say the cannon has a muzzle velocity of 1000 meters per second. The cannonball, therefore, has an initial velocity of 1000 m/s before it starts to slow down. Plugging 1000 into the equation above and solving for h, we calculate the theoretical maximum height as 51,020 meters. In practice, however, the cannonball will not achieve anywhere near that height because of air resistance, which has a tremendous effect at such high speeds.
Why does a gunner feel a backward jerk when firing a gun?
This is conservation of momentum. You have the hot gases from the explosive charge along with the bullet moving out the barrel, away from the person. Momentum is mass times velocity. While the mass of the bullet and gases are small, the velocity is very high. So nothing was moving before the trigger was pulled, so net momentum is zero. After the trigger is pulled, the momentum is still net zero. Any momentum away from the gunner will have an equal momentum (the gun recoiling) toward him. Since the gun has much more mass than the bullet, the velocity is much less.
What is the total momentum of the bullet and the gun after firing?
Exactly the same as whatever it was before firing. If the loaded gun was not movingbefore the trigger was pulled, then the total momentum of the gun and bullet afterfiring add up to zero.
Why was the ferry boat firing the cannon in Huckleberry Finn?
The ferry boat was firing the cannon to get the attention of a nearby steamboat and warn them about a potential collision. It was a way to alert the other boat and prevent an accident on the river.
