The forked rod is used to move the smooth 2-kg particle around the horizontal path in the shape of a limacon, r=0.3(2+cos ) m. If at all times 0=1 rad/sec, answer the following questions when the rod is at the instant 0=45. Note that the fork and path contact the particle on only one side. 1) Determine the magnitudes of a, and a, at the current position (0=45). (Hint: angular velocity is constant) 2) Determine the angle between the radial and tangential direction. r (Hint: tany= dr de 0.6 m, 3) Determine the force which the rod exerts on the particle at this instant (0=45'). 0.9 m-
