A collar that slides along a horizontal rod has a pin that is constrained to move in the slot of arm AB (Fig. P13-109). The arm oscillates with angular position given by 0(t) = 90 - 30 cos wt where w = 1.5 rad/s, t is in seconds, and is in degrees. For t = 5 s, a. Determine the radial distance from the pivot A to the pin B. b. Determine the velocity components vr and ve of the collar. c. Determine the acceleration components ar and a0 of the collar. d. Verify that the velocity vector v and the acceleration vector a are both directed along the horizontal rod. Fig. P13-109 2 ft r(t) 0(r)
