having trouble with this problem in my text book(adsbygoogle = window.adsbygoogle || []).push({});

two pucks collide, puck A has a mass of 0.32kg, and an initial velocity of 0.04 m/s [54 N of E], and a final velocity of 0.034 m/s [N]

puck B's mass is unknown but has an initial velocity of 0.038 m/s [S of W] and a final velocity of 0.028 m/s [46.5 N of E]. Puck B's mass needs to be found.

Wheni tried it i used components but i did not get the right answer, the answer in the back of the book is 0.22kg. Does anyone else get this answer? if so could you explain how?? thanx.
