Adrian Peterson is a running back for the Minnesota Vikings and weighs 980 N. During the game, he is running forward at +6 m/s when he runs into a linebacker who is running straight at Adrian with a velocity of -4.5 m/s. If the linebacker is 110kg and holds onto Adrian after the collision, what is their final velocity?

动量的问题嘛.98*6-110*4.5=v * (98+110),解出V即可.
