seeing as i tried that equation and apparently i still have the wrong answer...anyway i can get a step by step? i must be missing something?

A 78g particle moving with an initial speed of 39m/s in the positive x direction strikes and sticks to a 160g particle moving with 33m/s in the positive y direction. How much kinetic energy is lost in this collision? Answer in units of J. Can someone please tell me how to solve this...
