Question

Hi there, I only need help with parts d, e and f if possible. Thank you! 

A 230-kg crate hangs from the end of a rope of length L= 12.0 cm. You push horizontally on the crate w
a varying force F to move it distance d = 4.00 cm to the side, as shown.
(a) What is the magnitude of F when the crate is in this final position?
During the crate's displacement,
(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 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)?
