Like friction, the drag force always opposes the motion of an object. However, a small squirrel does this all the time, without getting hurt. For this reason, during the 1970s oil crisis in the United States, maximum speeds on highways were set at about 90 km/h (55 mi/h). Flocks of birds fly in the shape of a spearhead as the flock forms a streamlined pattern (Figure $$\PageIndex{3}$$). Table $$\PageIndex{1}$$ lists some typical drag coefficients for a variety of objects. For instance, consider a skydiver falling through air under the influence of gravity. A 75-kg skydiver descending head first has a cross-sectional area of approximately A = 0.18 m2 and a drag coefficient of approximately C = 0.70. Since $$F_D$$ is proportional to the speed squared, a heavier skydiver must go faster for FD to equal his weight. The position at any time may be found by integrating the equation for v. With v = $$\frac{dy}{dt}$$, $dy = \frac{mg}{b} \big( 1 - e^{- \frac{bt}{m}} \big)dt \ldotp$, $\int_{0}^{y} dy' = \frac{mg}{b} \int_{0}^{t} \big( 1 - e^{- \frac{bt}{m}} \big)dt',$, $y = \frac{mg}{b} t + \frac{m^{2}g}{b^{2}} \big( e^{- \frac{bt}{m}} - 1 \big) \ldotp$, Example $$\PageIndex{2}$$: Effect of the Resistive Force on a Motorboat. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Two situations for which the frictional force can be represented this equation are a motorboat moving through water and a small object falling slowly through a liquid. For most large objects such as cyclists, cars, and baseballs not moving too slowly, the magnitude of the drag force $$F_D$$ is proportional to the square of the speed of the object. Not to mention that your observations are not very rigorous, did you do an autopsy on the squirrel? I have seen a squirrel die from falling with my own eyes. Example $$\PageIndex{1}$$: Terminal Velocity of a Skydiver. The boat then slows down under the frictional force $$f_R = −bv$$. Suppose the resistive force of the air on a skydiver can be approximated by $$f = −bv^2$$. Q: The nearest star to our solar system is 4.29 light years away. Notice that the drag coefficient is a dimensionless quantity.
