Two ice skaters, each with a mass of 72.0 kg, are skating at 5.55 m/s when they collide and stick together. If the angle between their initial directions was 125o, determine the components of their combined velocity after the collision. (Let the initial motion of skater 1 be in the positive x direction and the initial motion of skater 2 be at an angle of 125o measured counterclockwise from the positive x-axis.)
