The power screw turns at a speed which gives the threaded collar C a velocity of 0.8 ft/sec vertically down. At the moment shown, collar C is decelerating downward at a rate of 1 ft/sec2. Determine the angular velocity and angular acceleration of the slotted arm when θ:30. Also find the velocity of slider C relative to the slotted arm. Use the rotating axes velocity equation and remember to specify the origin and rate of rotation(Q) of the rotating axes. (Answer: ω08-0.4 rad/s CCW. xy 0.4* from C to 0) В' 030 18"
