A barbell with two equal masses 1.0 kg on either end rotates about an axis perpendicular to the bar with an angular velocity of 1.13 rad/s. If one of the masses is 0.43 m away from the axis of rotation and the entire system has a rotational kinetic energy of 25.1 J, how far away is the other mass from that axis (in meters)? 

Note: Treat the weights on the barbell as point masses, so that you can use I = mr2
