Problem 74P A student on a piano stool rotates freely with an angular speed of 2.95 rev/s. The student holds a 1.25-kg mass in the outstretched arm, 0.759 m from the axis of rotation. The combined moment of inertia of the student and the stool, ignoring the two masses, is 5.43 kg -m2, a value that re

Consider the Dinks (double income, no kids). Mr. Dink commutes to a job in the city center (x=0), while Ms. Dink commutes to a suburban subcenter four miles east of the city center. The Dinks consume the same quantity of housing at all locations. Travel speed is the same in both directions. a . Draw
