Really, this is a classic projectile motion physics problem.

College is like a chocolate chip cookie, and courses—online or not—are the chocolate chips.

You might think this is just a boring physics problem—but you'd be wrong.

There are different categories of incorrect physics—and each deserves its own strategy.

Which method is better? It’s complicated.
