2.19 The cable, whose length is 250 mm, is fastened to the 500-g block. Clockwise rotation of the arm at a constant angular speed of 5 rad/s causes the block

to slide out-ward. The motion occurs in the vertical plane, and frictional resistance is negligible.Determine the tensile force in the cable and the force exerted by the block on the walls of the groove when 53.1301.
