[1 point, 10 tries] Four masses are connected by 19.5 cm long, massless, rigid rods. If mass A =149.0 g, mass B =223.0 g, mass C =233.0 g, and mass D =248.0 g, what are the coordinates of the center of mass if the origin is located at mass A? (Enter your x coordinate first followed by the y coordinate.) Answer: 1.10e-01 m 1.04e-01 m 2 . [1 point, 10 tries] What is the moment of inertia about a diagonal axis that passes through masses B and D. Answer: 7.26e-03 kg*m^2 3 . [1 point, 10 tries] An object's moment of inertia is 3.15 kg·m 2 . Its angular velocity is increasing at the rate of 4.87 rad/s per second. What is the torque on the object? Answer: 1.53e+01 N*m 4 . [1 point, 10 tries] A 1.21 kg ball and a 2.42 kg ball are connected by a 1.08 m long rigid, massless rod. The rod is rotating clockwise about its center of mass at 23.4 rpm. What torque will bring the balls to a halt in
