Military rifles have a mechanism for reducing the recoil forces of the gun on the person firing it. an internal part recoils over a relatively large distance and is stopped by damping mechanisms in the gun. the larger distance reduces the average force needed to stop the internal part. (assume the gun is fired in the positive direction.)
(a) calculate the recoil velocity (in m/s) of a 1.07 kg plunger that directly interacts with a 0.0200 kg bullet fired at 571 m/s from the gun. (indicate the direction with the sign of your answer.) 10.67 m/s (b) if this part is stopped over a distance of 18.2 cm, what average force (in n) is exerted upon it by the gun? (indicate the direction with the sign of your answer.) -334.66x n .
(c) compare this to the force exerted on the gun if the bullet is accelerated to its velocity in 12.4 ms.
