Chapt. 5 Newton’s Laws and Dynamics I 51 a) outside of the object. b) neither inside nor outside the object. c) at the point about which the object is symmetric in 2 of the dimensions, but not in the 3rd. d) at the point about which the object is symmetric in 1 of the dimensions, but not in the other 2. e) at the geometric center. 005 qmult 00630 2 5 1 moderate thinking: center of mass, 3-d symmetry 2 Extra keywords: Not a brilliant problem 24. The center of mass of an object is easily found if the object is: a) symmetric in THREE mutually perpendicular directions like, for example, a rectangular block. b) symmetric in TWO mutually perpendicular directions, but not in the third direction perpendicular to the first two. c) symmetric in ONE direction, but not in two mutually perpendicular directions that are perpendicular to the first one. d) completely irregular. e) made out of whipped cream. 005 qmult 00640 1 5 3 easy thinking: center of mass, symmetric sphere
