Question
Transcribed Image Text: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)
