Disk C R = 1 ft 3 ft C A x 2 rad/s B \60 The disk C is rolling to the right with an angular velocity of 2 rad/s. The bar AB connects the disk to collar through pins at A and B. For the configuration shown. (a) (10 pts) Determine the velocity vector of point A. (b) (10 pts) Determine the exact location of the instant center of rotation of bar AB (give the x and y coordinates of the instant center in using the reference frame shown.) (c) (10 pt) Determine the angular velocity of the bar. Clearly indicate the direction (either clockwise or counterclockwise). (d) (5 pt) Determine the velocity vector of the collar B.
