1. The 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. Determine the velocity and acceleration of the end of the cord at B if at the instant sA = 4 ft the collar is moving upward at 5 ft> s, which is decreasing at 2 ft> s2.

2. 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 sB = 6 ft, the end of the cord at B is pulled downward with a velocity of 4 ft> s and is given an acceleration of 3 ft> s2. Determine the velocity and acceleration of the collar at this instant.
