Question

two hockey players of opposite teams while trying to hit a hockey ball on the groung collide and immidiately become entangled . one has a mass of 60kg and was moving with a velocity 5.0 m/s while the other has a mass of 55 kg and was moving faster with a velocity 6.0 m/s towards the first player . in which direction and with what velocity will they move after they become entangled ? assume that the frictional force acting between the feet of the two players and ground is negligible
