Muzzle velocity will vary, depending on whether fired from a rifle, revolver, or semi-automatic pistol- and on the loading of THAT particular cartridge. A .38 Special wadcutter target load fired from a 4 inch bbl revolver will reach about 690 feet per second. A +P+ (high energy load) fired from a 6" revolver may reach 1100 fps.
If mechanical energy is conserved (like, if you did this on the Moon, where there is practically no air), when the bullet gets back to the ground it must have the same speed with which it started out. In practice, it will be less, due to air resistance.
One would think that .380 ACP and .38 Special would be the same size--namely 38-hundredths of an inch. But there can be some flexibility in stated caliber and actual caliber. Long story short, .380 ACP is the same diameter as a 9mm, roughly .355 caliber. .38 Special is basically .357 caliber.
Well the equation D=RT is how you get the distance an object will travel in the allotted time at the rate of travel. The distance is 38, and the time is 1.7, but you don't know the rate of travel. So, D/T=R is how you find the rate of travel. 38/1.7 = 22.352 m/s horizontal velocity.
A bullet hardly slows down at all after being fired. While bullets come in a variety of shapes, sizes and weights, they are all failry aerodynamic and thus minimally impacted by the wind resistance (friction). A bullet's primary enemy is actually gravity. Once fired, it is a matter of time before gravity pulls the bullet crashing down into the earth...assuming it does not strike something first. While a high powered rifle will send a bullet farther and faster than a .38 pistol, fired from the same height, at the same trajectory over level ground, they will have almost identical hang times. Again, the faster bullet will simply go farther. The speed loss for any bullet, (buck shot not included) is negligible. It will strike the ground or object in its way with almost the same speed as when it was fired no matter how far away it is. This is of course excluding shots in the air where there is little horizontal movement and the trajectory is mostly verticle. Here, obvioulsy, gravity will take over and the bullet will ultimately fall back to the ground at the terminal velocity - much slower than muzzle velocity.

caliber 38 is a caliber 38. bullet dia. is .357 caliber deals with the dia. or measurement around the bullet head, not the bullet case.
Close. a .38 caliber is usually closer to .357 caliber.
No. The bullet is too big. A 30-30 is a .30 caliber bullet. a .38 bullet is .357 caliber
A .38 caliber bullet typically has a diameter of approximately 9.1 millimeters. The designation ".38 caliber" refers to the bullet's diameter, which is often rounded to the nearest hundredth of an inch. Therefore, a .38 caliber bullet can be generally considered to be around 9 mm in metric measurements.
It depends on several factors, but a good rule of thumb is "about a mile."
.38 Special, yes. Other .38 cartridges (such as the .38 Long Colt or .38 Super), no.
Depending on what it is chamberd for, yes.
38 is the size. This answer is actually correct, but more specifically, .38 special (and many of the other .38 caliber cartridges) are actually .357. The caliber ".38" was chosen to distinguish between .357 magnum and .38 special.
Any that have the appropriate sized barrel
Well, yes and no. Both the .357 Magnum and the earlier .38 Special catridge both use a bullet that is .357 inches in diameter. The .38 Special in not a TRUE .38 caliber cartridge.
Yes
The actual bullet diameter (as well as that of the .38 Special) is .357.
