One soccer player (m1 = 65kg) is traveling with a velocity of v1 = (4.5 j) m/s. this player collides with a second player who has a mass of m2 = 72 kg who is traveling with a velocity of v2 = (3.3 i - 2.2 j) m/s. the players tangle together when they collide (a totally inelastic collision). what is the speed of the combined mass just after the collision? give your answer in unit vector notation.
