Your new picture should be this one:

Zoomed Comparison Plot

The upper, red, plot is the actual solution, so apparently, the linearized, blue, solution "undershoots" reality, and would be untrustworthy as a model for this higher initial velocity problem.

What if We Use Really Large Values For y?

Now redo the entire problem a third time, and this time let's really wallop the thing, giving it an initial velocity, vo, of 10. Don't forget to keep the colors differentiated!

Welcome back. Let's go look at the picture which you should have gotten...
