The forked rod is used to move the smooth 1.2-lb particle around the horizontal path in the shape of a limaçon, r = (2+ cos) ft. (Figure 1) Figure -3 ft 1 of 1 Part A If 0 = = (0.5t²) rad, where t is in seconds, determine the force which the rod exerts on the particle at the instant t = 1 s. The fork and path contact the particle on only one side. Express your answer to three significant figures and include the appropriate units.
