The slider block B moves to the right with a constant velocity of vB = 65 [in/s]. Q8: Determine velocity of block A, vA [in/s]. Q9: Determine velocity of portion D of the cable, vD [in/s]. Q10: Determine relative velocity of A with respect to B, vA∣B [in/s]. Q11: Determine relative velocity of portion C of the cable with respect to portion D, vC∣D [in/s].
