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 va = 3.4 ft/s at sA = 2.1 ft. In your answer, negative sign must be included if the motion of B is 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. Datum SB B 3 ft 3 ft VA VA SA A Your Answer: Answer units
