The masses and coordinates of four particles are as follows: 50 g, x = 2.0 cm, y = 2.0 cm; 25 g, x = 0, y = 4.0 cm; 25 g, x = -3.0 cm, y = -3.0 cm; 30 g, x = -2.0 cm, y = 4.0 cm. What are the rotational inertias of this collection about the
(b) y, and
© z axes?
(d) Suppose that we symbolize the answers to
(b) as A and B, respectively. Then what is the answer to
© in terms of A and B?
