The weight of the 5. This means I cannot ignore air resistance. Here is another plot. This is the same as above except I have added a similar plot of the starting velocities in the case where air resistance is included.
Hint: The green line is no air resistance. So, what was the "starting speed"? Of course this assumes the ball hit the first house without bouncing. I wouldn't be surprised if it did bounce. This is one of my favorite things to point out: Things don't scale like you would expect. I don't know why we expect this, but we do. You I at least always think something like:. A bullet has about the same density. Sure it will have a lower mass, but it will also have a smaller air resistance force. I guess a bullet and cannonball shot with the same speed will go about the same distance.
There are essentially two forces to consider. The gravitational force depends on the mass. For objects with the same density, the mass is proportional to the volume which is proportional to the cube of the radius.
The air resistance force depends on the cross sectional area of the object. In this case, that looks like a circle. The area of a circle is proportional to the radius squared. So consider a bullet with a radius r. If I double the radius, the weight will be 8 times as much. The air resistance for the same speed as the smaller bullet will just go up by a factor of 4.
Gunpowder would be put into the bottom of the mortar, and then the shell put on top of it, fuse upwards. The crew would light the fuse, and then fire the mortar, sending the shell to drop almost straight down in the middle of the enemy, where it would explode, sending bits of its casing through the enemy personnel. Punching through a mass of soldiers, a round shot could kill or main dozens. They could also travel hundreds of metres by skipping across the ground, or rolling along breaking legs and ankles.
However, the ground was very wet during most of the Battle of Waterloo, meaning the cannons were much less deadly than usual. Civil War Springfield Model Rifle. Henry Repeating Rifle. LeMat Pistol. Gatling Gun. What kind of trajectory does it make? If we ignore air resistance and the curvature of the earth the answer is that the trajectory is parabolic. This classical curve is an excellent first approximation to understanding the motion of a wide range of projectiles, from boulders tossed by catapults to baseballs.
Want to keep learning? Q2 E : One of the pleasant consequences of knowing that a trajectory is parabolic is that we can use what we know about the geometry of a parabola to say something about the trajectory. Where did it reach its maximum? Q3 M : This analysis is all very well, but it certainly does not apply to a boomerang. Why not? A key question for artillery is at what inclination to fire a cannon or gun to maximize range. The particle would just shoot off into space exactly in the direction you fired it, at a constant speed.
We know that the maximum of a parabolic function occurs exactly half-way between its zeros. In this case the zeros are where the cannonball is at ground level, namely the place of firing and the place where it lands.
They could be worth something to a museum or a collector or they could be your newest paperweights. The maximum range for howitzers [which fired roundshot at this range] was between 1, and 1, yards but their maximum effective range was around yards for the light calibres.
British practice was to fire shrapnel or roundshot at ranges over yards. This is pretty much what most artillery rounds are today. The typical Civil War shell had a range of about 1, yards — or just under a mile. Unknown Team. Coverage limited to news reporting as of May The Cannonball Run: A journey and a race, run at warp speed. Or about 80 mph. Police officers often know cars well, Tabbutt said, but the countermeasures are designed to confuse even if just for a moment, which could make the difference if they are pulled over.
On the other hand, larger cannons such as the ones on early dreadnoughts, could easily destroy a modern tank. As with all things, it depends on what cannon you are using. The first successful rapid-fire firearm is the Gatling Gun, invented by Richard Gatling and fielded by the Union forces during the American Civil War in the s. Harquebus, also spelled arquebus, also called hackbut, first gun fired from the shoulder, a smoothbore matchlock with a stock resembling that of a rifle.
The harquebus was invented in Spain in the midth century. It was often fired from a support, against which the recoil was transferred from a hook on the gun.
