- | * **Question: | + | * **Question:**The mechanism breaks and a tuber is stranded on the hill. How would the work done by the mechanism change if the tube was pulled at an angle from the second floor of the lodge at the top of the hill? Illustrate what will happen with a force vs. distance graph and a work vs. distance graph that models this situation. |
