**These assumptions made in this calculation:**

Head on collision

Bird is riding with the airliner after the collision

Birdâ€™s velocity is negligible compared to that of the airliner

Total time taken to crush the bird (estimated impact time) = Length of the bird / Speed of the airliner

Impulsive applied to the bird

**Impulse**

Useful conversion you may need in this kind of problem

**Force**

1 lb = 4.45 N

1 N = 1 kg m s

^{-2}

1 N = 105 dyne = 0.225 lb

**Mass**

1 kg = 2.20 lb (where g = 9.8 ms

^{-2})

**Speed**

1 mi/h = 1.47 ft/s = 1.61 km/h = 0.447 m/s

1 km/h = 0.278 m/s = 0.621 mi/h = 0.911 ft/s

**Length**

1 ft = 30.5 cm

1 m = 3.28ft

1 mi = 5280 ft = 1.61 km

1 km = 0.621 mi

*( mi = mile, ft = feet, km = kilo meter, m = meter, h = hour, s = second )*
