A bullet is fired through a 14.0 mm thick barrier, with its line of motion being perpendicular to the face of the barrier. If it enters with a speed of 450 m/s and emerges with a speed of 220 m/s, what was the bullet's acceleration as it passed through the barrier

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
