Q8. As shown in the image below, objects A and B connected by a rope with fixed length of 7 ft. For absolute dependent motion
analysis, the datum line and the position variables for A and B, SA and SB, are also provided. Assume the rope never has any slack,
determine the velocity of object B when the velocity of object A is VÀ = 4.4 ft/s at sà = 4.5 ft. In your answer, negative sign must be
included if the motion of Bis opposite to the direction of its given position variable. Please pay attention: the numbers may change
since they are randomized. Your answer must include 2 places after the decimal point, and proper unit.
