tricky question??? This question comes from an old test that a University in my area gives out to highschools to see who is out there, and possibly give them a scholarship. A person is on a boat in the ocean next to an island. On that island there is another person and a tree. There is a rope tied between the boat and the tree. The person on the boat can pull himself in at 1 m/s. and the person on the island can pull the boat in at 1 m/s. If both people pull at the same time on the rope, how fast will the boat be moving towards the island. Warning spoilers. | | | | | | | | | | | I was told that the answer is that the boat will move at 1 m/s. Logically to me the boat would move at 2m/s. I don't see where I am going wrong.
