The figure below shows a ship, $A,$ which has gotten stuck sideways in a canal and is blocking all the other traffic in the canal. The ships is anchored to the shore at point $B.$ A tugboat has been dispatched to the scene to help straighten out the the ship. The thrust of the tug boat is limited to $500,000lb.$ It can attach a line to the ship at point $C.$ The captain of the tugboat is trying to decide which direction would make it easiest to rotate the ship about its anchor point, $B,$ and straighten the ship out and open up the canal to traffic.

Which of the three directions shown would allow the tugboat to best use its limited thrust to rotate the ship about the anchor point $B?$

Direction $1$

Direction $2$

Direction $3$

They all would be equivalent
