Weapon Recoil Simulation

  1. May 9, 2007 #1
    I need to do a rifle recoil simulation to some weapon sights. I have two of them. One weighs 2.2 lbs and the other 2.6 lbs. I need them to be going 2.2 meters a second when the hit the ground.

    How high do I have to drop each one?

    Seems like a strange thing to do to a rifle.

    Objects accelerate downward at g (9.81 m/s2), which is the acceleration of gravity at sea level. If an object starts are rest and falls, then one can use conservation of energy - gravitational energy (mgh) becomes kinetic energy (1/2 mv2), or

    mgh = 1/2 mv2, which can be simplified to find h as a function of v.
