A 32-u oxygen molecule (O2) moving in the +x direction at 580 m/s collides with an oxygen atom (mass 16 u) moving at 870 m/s at 27 degrees to the x axis. The particles stick together to form an ozone molecule. Find the velocity of the ozone. Express your answer in terms of the units vectors i and j.

I know my i is 645 and my J is 132 but for my answer do I just put fo my final velocity i=645m/s
