6.59. Set Up: The planet has mass and density The volume of a sphere is Solve: (a) so (b) Reflect: so g is proportional to for planets of the same density. m is larger by a factor of 14 compared to earth, so g is larger by a factor of 6.60. Set Up: On earth, On Mars, The artificial gravity acceleration is Solve: (a) (b) (c) The free-body diagram is given in Figure 6.60. The diagram is drawn for when the rim of the station is to the right in the figure. Figure 6.60 6.61. Set Up: The earth has mass radius and rotational period Use coordinates for which the direction is toward the center of the earth. The free- body diagram for Sneezy at the equator is given in Figure 6.61. Figure 6.61 Solve: At the north pole Sneezy has and the gravitational force exerted by the earth. Sneezy has mass w / g 5 48.47 kg. T 5 w 5 475.0 N, a 5 0 x y w 5 mg T a rad 1 y T 5 24 hr 5 8.64
