A300 g bird is flying along at 6.0 m/s and sees a 10 g insect heading straight towards it with a speed of 30 m/s. the bird opens its mouth wide and swallows the insect. a. what is the birds speed immediately after swallowing the insect? b. what is the impulse on the bird? c. if the impact lasts 0.015 s, what is the force between the bird and the insect?

(a): The bird speed after swallowing the insect is V= 4.83 m/s

(b): The impulse on the bird is I= 0.3 kg m/s

(c): The force between the bird and the insect is F= 20 N

Explanation:

ma= 0.3 kg

va= 6 m/s

mb= 0.01kg

vb= 30 m/s

(ma*va - mb*vb) / (ma+mb) = V

V= 4.83 m/s (a)

I= mb * vb

I= 0.3 kg m/s  (b)

F*t= I

F= I/t

F= 20 N (c)

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
