The 16-ft-long cord is attached to the pin at Cand 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 4.2 ft/s and is given an acceleration of 3 ft/s². (Figure 1) Figure SA UC 3 ft 3 ft B < 1 of 1
Determine the velocity of the collar at this instant. Express your answer to three significant figures and include the appropriate units.
