If the rod AB rotates counterclockwise with an angular velocity o = 8 rad / s, calculate the velocities of the C and D blocks at the moment shown in the figure below.

The 16-ft-long cord is attached to the pin at C and passes over the two pulleys at A and D. The pulley at A is attached to the smooth collar that travels along the vertical rod. When sp = 6 ft, the end of the cord at B is pulled downward with a velocity of 3.7 ft/s and is given an acceleration of 3 ft/s². (Figure 1) Figure SA -3 ft -3 ft B D SB ▶ Determine the velocity of the collar at this instant. Express your answer to three significant figures and include the appropriate units.

P4. In the Figure, the washer is sliding outward on the rod with a velocity of 3 m/s when its distance from point O is 2 m. Its velocity along the rod is increasing at the rate of 8 m/s. The angular velocity of the rod is 2 radis counterclockwise, and its angular acceleration is 10 rad/s clockwise. Determine the absolute velocity and acceleration of point P on the washer.
