The document describes the motion of body C in a diagram. Body B moves at a constant velocity of 0.25 m/s along AD. Body C descends with a velocity of 0.5 m/s and acceleration of 0.8 m/s^2. Arm AD rotates with angular velocities of 0.4 rad/s and angular acceleration of 0.6 m/s^2. The velocity and acceleration of body C at the instant shown are calculated to be 0.56 m/s and 0.8 m/s^2, respectively.
