Homework Statement

It's that exact problem, except I need the latter parts to it.
(a) What is the position of the block?
m
(b) What is the work that has been done on the block by the applied force?
J
(c) What is the work that has been done on the block by the spring force?
J
During the block's displacement, find the following values.
(d) The block's position when its kinetic energy is maximum.
m
(e) The value of that maximum kinetic energy.
mJ
The Attempt at a Solution
I solved A by myself from Fx = 1/2kx^2. Solved for x.
Then for C, I did -1/2kx^2. And B = 1/2kx^2.
I need parts D and E. How would I go about solving them? I know that deltaK = Kf - Ki = W(applied force) + W(spring).
