A 230 kg crate hangs from the end of a rope length L=12.0 m. You push horizontally on the crate with a varying force F to move it distance d=4.00m to the side. A: What is the magnitude of F when the crate is in this final position? During the crate's displacement, what are B:the total work done on it, C:the work done by the gravitational force on the crate, and D: the work done by the pull on the crate from the rope? E: Knowing that the crate is motionless before and after its displacement, use the answers to B, C, and D to fine the work your force F does on the crate. F: Why is the work of your force not equal to the product of the horizontal displacement and the answer to A? I am clueless....please help!
