To protect their young in the nest, peregrine falcons will fly into birds of prey (such as ravens) at high speed. In one such episode, a 550g   falcon flying at 20.0m/s   hit a 1.50kg   raven flying at 8.0m/s . The falcon hit the raven at right angles to its original path and bounced back at 5.0m/s . (These figures were estimated by the author as he watched this attack occur in northern New Mexico.)

Explanation / Answer

the falcon bounces back at 5 m/s this gives you the 2 equations:

0.55*20=-5*0.55+pfx
-1.5*8=pfy

therefore pfx=13.75 kgm/s and pfy=12kgm/s
=arctan(12/13.75)
= angle of 41.11 degrees.

as for speed just do the magnitude of the momentum
=sqrt(13.75^2+12^2)
=18.25
now divided by the mass of the raven
=18.25/1.5
raven's speed after collision=12.16 m/s
