Question

Consider a square of mass 4.00 kg, with side 2.00 m, negligible thickness, with its sides

oriented along the usual axes with its center at the origin (0, 0).

a)Determine its CM using symmetry arguments.

b)Imagine that the 1m×1m part of it in the fourth quadrant is chopped off. Where is the new CM?

c)Repeat using the following trick: view the chopped off shape as a full square plus a 1m×1m square of negative mass−1.00 kg in the fourth quadrant.
