Since the problem asks for a relationship between the change of speeds of A and B, and the distance traveled by B, the work/energy equation is a natural method of choice. Recall that with the ...
Draw a free body diagram for the entire system of A+B+bar. Which, if any, forces do non-conservative work on this system? Can you justify this from the FBD? Step 2: Kinetics (work/energy equation) ...
