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

Consider the rapid steady precession of a symmetric top predicted in connection with (10.112). (a) Show that in this motion the angular momentum L must be very close to the verti-cal. [Hint: Use (10.100) to write down the horizontal component Lhor of L. Show that if is given by the right side of (10.

Integration and Segregation Consider a city of 200 people (100 tall and 100 short) and two neighborhoods (100 people in each). People generally prefer to live close to short people. To draw the rent-premium curves, put the number of short people in neighborhood A (from 50 to 100) on the horizontal ax
