Answer:
V = 2.8 m/s
Explanation:
It is given that,
Mass of falcon, 
Mass of dove, 
Initial velocity of falcon, 
Initial velocity of dove, 
When the falcon catches the dove, the momentum remains conserved. Using the formula for the conservation of momentum as :

V is the velocity after impact


V = 2.8 m/s
So, their velocity after the impact is 2.8 m/s. Hence, this is the required solution.
