A 3 kg object going at 2 m/s run into another 5 kg object going at 4 m/s in the opposite direction. What was the final velocity of the two objects if they got stuck and moved together after the collision? V = (m1u1 - m2u2)/(m1 + m2)

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?
