Question
A 300 g bird flying along at 5.7m/s sees a 10 ginsect heading straight toward it with a speed of 34m/s (as measured by an observer on the ground,not by the bird). The bird opens its mouth wide and enjoys a nice lunch. Part A What is the bird's speed immediately after swallowing?

Part A What is the bird's speed immediately after swallowing?Explanation / Answer
from conservation of momentum
0.3(5.7) + 0.010(-34) = (0.3+0.010) V
V = 4.42 m/s
