A 300 g bird flying along at 6.2 m/s sees a 10 g insect heading straight toward it with a speed of 35 m/s (as measured by an observer on the ground, not by the bird). The bird opens its mouth wide and enjoys a nice lunch. Required:
What is the bird's speed immediately after swallowing?

The velocity of the bird is

Explanation:

From the question we are told that  

    The mass of the bird  is

    The initial speed of the bird is  

     The mass of the insect is

       The speed of the insect is

The negative sign is because it is moving in opposite direction  to the bird

According to the principle of linear momentum conservation

substituting values

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
