Chapt. 5Newton’s Laws and Dynamics I51a) 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 the3rd.d) at the point about which the object is symmetric in 1 of the dimensions, but not in theother 2.e) at the geometric center.005 qmult 00630 2 5 1 moderate thinking: center of mass, 3-d symmetry 2Extra keywords:Not a brilliant problem24. The center of mass of an object is easily found if the object is:a) symmetric inTHREEmutually perpendicular directions like, for example, a rectangularblock.b) symmetric inTWOmutually perpendicular directions, but not in the third directionperpendicular to the first two.c) symmetric inONEdirection, but not in two mutually perpendicular directions that areperpendicular 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
