A comet of mass m moving with a velocity of +v0 collides inelastically with another comet of mass 4m initially moving with a velocity of -0.5v0. If the comet of mass m has a final velocity of +0.5v0, then determine the final velocity of the other comet in terms of v0. (e. g. the final comet has a velocity of +0.75v0)

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
