I'm kinda having trouble with this problem. can n e one help me out? Two ice skaters undergo a collision, after which their arms are intertwined and they have a common velocity of 0.85 m/s [27° S of E]. Before the collision, one skater of mass 71 kg had a velocity of 2.3 m/s [12° N of E], while the other skater had a velocity of 1.9 m/s [52° S of W]. What is the mass of the second skater? I tried to use the law of conservation of momentum and maybe draw a vector diagram, but i only have one momentum that i can actually calculate now. How can i do this (preferably without using components)?
