Three Children are trying to balance on a seesaw, which consists of a fulcrum rock, acting as a pivot at the center, and avery light board 3.6 m long. Two playmates are already on either end. Boy A has a mass of 50kg, and girl B a mass of 35 kg. Where should girl C, whose mass is 25 kg, placed herself so as to balance the seesaw.

A 230kg crate hangs from the end of a rope of length L=12.0m. 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? 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 fromthe rope? e) Knowing the 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. f) Why is the work of your force not equal to the product of the horizontal displacement and the answer to (a)?
