Ok...so I am physics phobic! I read these physics questions and honestly have no idea what they are even asking. I have no idea how to start or what to do. I understand that this forum is for assistance for homework, but what do you do when you haven't a clue on how to even begin? So I am looking for help on how you start with a problem like this: You have a 10.0kg rock with a rope tied around it. What acceleration would you give the rock if you pull upwards on the rope with a force of 100 N? How can I get an answer when I don't even know how far the rock traveled? Wouldn't I need to know that in order to answer the question? Please help!
