Question

Two football players of opposite teams, while trying to hit a ball on the ground collide and immediately entangled each other. One Player having mass 65 kg was moving with 6m/s while other having mass 70 kg and was moving with velocity 7 m/s. both were moving in same direction. Find the velocity of both players with direction after they become entangled? Neglect Frictional Forces.
