A320 g bird flying along at 7.0 m/s sees a 12 g insect heading straight toward it with a speed of 30 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. what is the bird's speed immediately after swallowing?

To solve the problem it is necessary to apply the conservation equations of the moment.

The conservation equation of the moment is defined as,

Where,

Mass of Bird

Mass of Insect

Velocity Bird before swallowing

Velocity of insect

final velocity (both)

Replacing with our values we have,

Therefore the bird's speed immediately after swallowing is 7.83m/s

the body's situation won't change the forces are equal opposit and on the same body

answer: good job it's all correct !
