A uniform rod of length 0.80 m is fixed to a massless axle on one of its ends such that its rotational axis is perpendicular to its length. The rod's moment of inertia about the axle is 0.0410 kg•m². The rod is rotating at 1.40 rads/s when a remote-controlled movable mass slides from very close to the axle to the opposite end of the rod. The mass has a linear speed of 0.980 m/s when located at the opposite end. Determine the mass of the rod. You may treat the mass as a particle.
