Many birds can attain very high speeds when diving. Using radar, scientists measured the altitude of a barn swallow in a vertical dive; it dropped 208 m in 3.0 s. The mass of the swallow was estimated to be 0.018 kg, and its cross-section area as 5.6×10−4m2. What was the drag coefficient for this swallow as it dove?

The drag coefficient of a sparrow is required.

The drag coefficient is 0.107.

d = Distance = 208 m

t = Time = 3 s

= Density of air =

A = Area =

m = Mass of bird = 0.018 kg

g = Acceleration due to gravity =

c = Drag coefficient

Velocity of the bird

The drag force will be equal to the gravitational force.

The drag coefficient is 0.107.
