Two bodies, (OABC and CD) are in fixed rotation and touch at non slip point C. Point A is known to have instantaneous velocity of 3m/s which is decreasing at 0.5m/s^2.

Find:

?OABC (=10 rad/s -k)

vector ab in both t,n (of B) and x,y coordinates A. In XY: at= and an= m/s2 B. In tn: at= and an= m/s2

?OABC (=1.667 rad/s +k)

?CD (=20 rad/s +k)

VA-3m/s (decreasing @ 0.5 m/s) A B 0.3m 0.4m C D 0,2m
