Answer:
22.11 m / s 
Explanation:
The falcon catches the prey from behind means both are flying in the same direction ( suppose towards the left )
initial velocity of falcon = 28 cos 35 i - 28 sin 35 j  
( falcon was flying in south east direction making 35 degree from the east )
momentum = .9 ( 28 cos 35 i - 28 sin 35 j  )
= 20.64 i - 14.45 j 
initial velocity of pigeon 
= 7 i 
initial momentum = .325 x 7i 
= 2.275 i 
If final velocity of composite mass of falcon and pigeon be V 
Applying law of conservation of momentum 
( .9 + .325) V = 20.64 i - 14.45 j +2.275 i 
V = ( 22.915 i - 14.45 j ) / 1.225
= 18.70 i - 11.8 j 
magnitude of V
= √ [  (18.7 )² + ( 11.8 )²] 
= 22.11 m / s
