Homework Statement


The second picture contains the problem statement.
I am having a bit of trouble drawing the graphs asked for.

The Attempt at a Solution


I have drawn what I think is correct. In the first graph, I show the flux of the cart must increase from a to a/2 and go down to zero at point b. I have then used the same idea from b to a, but I am unsure if this is correct. I have modeled the rate of change in the second graph linearly, but I would like to know if it should be a trigonometric model.

Any help would be appreciated.

Your rate drawing is incorrect.

The rate of flux is just the slope of the flux. So graph the slope of the top figure onto the bottom figure.
