A 200 kg crate hangs from the end of a rope of length L = 13.0 m. You push horizontally on the crate with a varying force F to move it 4.00 m to the side. What is the magnitude of F when the crate is in this final position? N During the crate's displacement, what is the total work done on it? J During the crate's displacement, what is the work done by the weight of the crate? kJ During the crate's displacement, what is the work done by the pull on the crate from the rope? J Knowing that the crate is motionless before and after its displacement, use the answers to (b), (c), and (d) to find the work your force F does on the crate. kJ Why is the work of your force not equal to the product of the horizontal displacement and the answer to (a)?
