In an intense battle, gunfire is so intense that bullets from opposite sides collide in midair. Suppose that one (with mass M= 5.12 g moving to the right at a speed V= 214 m/s directed 21.3 degrees above the horizontal) collides and fuses with another with mass m = 3.05 g moving to the left at a speed v = 282 m/s directed 15.4 degrees above the horizontal.

What is the direction (degrees) of their common velocity immediately after the collision? (measure this angle from the horizontal)

The x component that I calculated is 23.45
The y component is 20.76

Beyond that, I am not quite sure how to get the right answer.

Work this in conservation of momentum, work in x, y directions.
