So would I, Lance- and I have been a serious collector for many years. The problem is, there are thousands of different calibers, with millions of different loadings (bullet/powder) that will produce different velocities and trajectories. And there is no ONE list. However, if you are seeking information on a particular caliber, pleae post that here, and we will try to help.
acceleration
if it slows down or reverses direction.
No. It always indicates that the object is not accelerating.
No. It always indicates that the object is not accelerating.
A velocity-time graph is often a misnomer since it is, in almost all cases, a graph showing the component of velocity in the direction towards and away from a fixed point of reference. The graphs do not usually included any information on the motion in a perpendicular direction. Therefore, a straight line in a "velocity"-time graph indicates that there is no acceleration in the radial direction.
Velocity is measured by distance traveled divided by the time taken to travel. Unlike speed Velocity contains vectors, which means you can have a negative velocity. For example if a car traveled to the right 6 meters in 3 seconds velocity would be 2 meters per second or 2 m/s An example showing the vector (Direction) would be a car traveled 6 meters to the left in 3 seconds. -6/3= -2 m/s
a car accelerates at a rate of 5 m/s^2 find its increasing velocity in 2 s
the person is walking at a constant velocity

I assume you are referring to RF/HF attenuation in the ionosphere. If that is the case, the attenuation is very complex depending upon the trajectory of the signal of interest. Attenuation is created by the free ions in the ionosphere and these values are different for each of the ionospheric layers plus it depends upon season and time of day. The conductivity of the ionosphere is a tensor showing that the attenuation is dependent on the wave trajectory. There is no simple answer for this. Look up normal, Hall, and Pedersen conductivities to help give you some insight into the challenge of this calculation.
It is the equation showing the relationship betweene, the electromagnetic force (EMF) generated between the ends of a straight conductor of length L, when it is moved with a velocity v, through a magnetic field of flux of density B.
