A 1.45 kg falcon catches a 0.515 kg dove from behind in midair. What is their velocity after impact if the falcon's velocity is initially 26.5 m/s and the dove's velocity is 4.95 m/s in the same direction?

Their velocity after the impact is 20.85 m/s.                            

Explanation:

Given that,

Mass of falcon,

Mass of dove,

Initial speed of the falcon,

Initial speed of the dove,

We need to find the final velocity after the impact. When the falcon catches the dove, it will becomes the case of inelastic collision. The conservation of momentum will be :

So, their velocity after the impact is 20.85 m/s.
