A spherical asteroid with radius r = 123 m and mass M = 2.25 × 1010kg rotates about an axis at four revolu- tions per day. A “tug" spaceship attaches itself to the asteroid's south pole (as defined by the axis of rotation) and fires its engine, applying a force F tangentially to the asteroid's surface as shown in Fig. 8–65. If F = 285 N, how long will it take the tug to r = 123 m rotate the asteroid's axis of rotation through an angle of 5.0° by this method? FIGURE 8–65 F = 285 Ni Problem 93.
