Consider an object that is coasting horizontally (positive x direction) subject to a drag force f = by cv2. Write down Newton's second law for this object and solve for v by separating variables. Sketch the behavior of v as a function of t. Explain the time dependence for t large. (Which force term i

a) By examining the effective potential energy (8.32) find the radius at which a planet (or comet) with angular momentum can orbit the sun in a circular orbit with fixed radius. [Look at dUeff I dr 1 (b) Show that this circular orbit is stable, in the sense that a small radial nudge will cause only s

Heli-Segways for Workers Consider a region with 6 million workers and two cities (A and B), each with an initial workforce of 3 million (the utility-maximizing workforce). Suppose the heli-segway (a fl ying personal transporter) replaces the automobile, cutting commuting cost and increasing the utili
