The spool, which has a mass of 4 kg, slides along the rotating rod. At the instant shown, the angular rate of rotation of the rod is = 5 rad/s and this rotation is increasing at = 3 rad/s². At this same instant, the spool has a velocity of 2 m/s and an acceleration of 2 m/s², both measured relative to the rod and directed away from the center O when r = 0.6 m. (Figure 1) Part A Determine the magnitude of the radial frictional force exerted by the rod on the spool at this instant.
