Biologists have estimated the drag coefficient of a swimming penguin by observing the rate at which a penguin’s speed decreases in its glide phase, when it’s not actively swimming and is slowing down. In one study, a gliding 4.8 kg Gentoo penguin has an acceleration of -0.52 m/s2 when its speed is 1.60 m/s. If its frontal area is 0.020 m2, what is the penguin’s drag coefficient?

The drag coefficient C in FD=12CAv2 (Eq. 6.5) depends primarily on the shape of the object. You already have developed an intuition about what shapes correspond to a low C by observing the shapes of aerodynamic cars, boats, and even bullets. Which object, a sphere or a cube, would have a larger drag coefficient, assuming they are nearly the same size? Explain your reasoning. What aspect of an object most determines its drag coefficient?
A 75.0-g arrow, fired at a speed of 110 m/s to the left, impacts a tree, which it penetrates to a depth of 12.5 cm before coming to a stop. Assuming the force of friction exerted by the tree is constant, what are the magnitude and direction of the friction force acting on the arrow?
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 x 10-4 m2. What was the drag coefficient for this swallow as it dove?
heeelp meee A shuttlecock is launched from the ground with an initial speed of 31.8066 m/s at an angle of 7.4391 degrees with respect to the horizontal. The shuttlecock experiences air resistance with a drag coefficient of 0.2742 in an environment where the air density is 0.6066 kg/m3. If the shuttlecock has a radius of 3.4 cm and a mass of 5.2 grams, what is the maximum height reached by the shuttlecock? Assume that the experiment is done near the surface of the earth.

Running on a treadmill is slightly easier than running outside because there is no drag force to work against. Suppose a 60 kg runner completes a 5.0 km race in 19 minutes. The density of air is 1.20 kg/m3 Determine the drag force on the runner during the race. Suppose that the runner has the cross section area of 0.72 m2 and the drag coefficient of 1.2. What is this force as a fraction of the runner's weight?
