9. If a horizontal force is applied to an object, how can you tell if an object will start moving? Your answer: O The object will start moving if any force is applied. O The object will start moving if the applied force is greater than the maximum static friction. O The object will start moving if the applied force is greater than the minimum static friction. O The object will start moving if the applied force is greater than the maximum kinetic friction. O The object will start moving if the applied force is greater than the minimum kinetic friction.

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?
Lisa measured the coefficient of static friction between two pairs of running shoes and the track in Example 6.1 (page 159). If she wants to have an advantage in a race, which shoes should she wear, the ones with a high coefficient or the ones with the low coefficient of static friction? Explain.
