A 3.0 kg rifle is held firmly by a 50.0 kg woman, initially standing still. A 0.06 kg bullet leaves the rifle muzzle with a velocity of 600 m/s. With what final velocity will the woman and rifle recoil?
(please put work when you post I need it for a quiz!) :)

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

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

The heliocentric and the geocentric models of the solar system included these central principles
