Sarah was attempting to pull the cart seen here through point A in the diagram. She could not do it. Her sister suggested setting up a pulley system to help Sarah with the task. The girls added the pulleys and ropes you see here. How did this pulley system help Sarah move the cart?
Because it moved the cart from the place were it was to were it needs to be.The Pully system also helped Sarah move the cart becuase it made the job easier to do.
