https://www.physicsforums.com/showthread.php?t=77424

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

3. 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).
