Two identical spools are held at the same heights above the floor. The thread from the spool A is tied to an overhead support while spool B is not connected to the support. An X is marked on the floor directly beneath each spool. Both spools are released at the same instant.

b) will spool A strike the floor to the left, right, or directly on the X? Justify your answer.
