Dependent motion - cable (rope) velocity

[leonel]

Hi, fellows !
In an arrangement of 2 slinding blocks connected by a cable (rope). I can state the blocks position and their velocity as a consequence. On the other hand, i can't figure out the cable velocity...which concept should I apply for ?


VB=18in/s > (Info)
VA= 27 in/s > (found)

What about the cables D and E velocity ?
Cable C has the same veloc of block B.

Thanks, Leonel

I would say the cable velocity is equal to the velocity of B.
