    How to calculate the velocity of a bullet fired by a rifle?

    we ignore for now the friction and the final speed of the bullet. I know the final speed formula my question is you have initial acceleration and the mass of the bullet. there is no distance or time involved yet. we have only the initial acceleration and the mass. since there is...

    How to calculate the velocity of a bullet fired by a rifle?

    Hi everybody, I'm trying to calculate the spontaneous energy of a projectile fired by a rifle, handgun, or a canon. The amount of the powder in the cartridge is known and with a reasonable assumption of the following we can calculate the initial pressure produced in the chamber as the rifle...

    Equation of Curve Using Arc Length and Two Points

    Baseline and offsets are used better in the field. So, if you have a base line and offset, specially the offsets are in x direction, then your baseline is the y direction. Assuming it's a simple curve, you can just use the offset and base as coordinates. Hence, you can find the cord and half...

    What is the Initial Speed Formula for a Ballistic Pendulum?

    This is a method in the field to measure the initial velocity of a firearm. When the bullet exits from the barrel, it has a kinetic energy of E=1/2 x m x V^2. As the bullet hits the ball, the whole kinetic energy becomes the potential energy causing the ball rise to a certain elevation, which...
