What the?

In a recent prep sheet for mathematics exam at Washington State Community College, students found the following question:

"25: Condoleeza holds a watermelon just over the edge of roof of the 300-ft Federal Building, and tosses it up with a velocity of 20 feet per second. The height of the watermelon above the ground t seconds later is given by the formula h=-16t^2 + 20t + 300."
Are you as outraged over this question as I am? I mean, seriously, what is the professor thinking? What could have possibly been going through his mind when he made that question? Come on! Everybody knows that the acceleration due to gravity is 32 feet per second, not 16! The equation should have been h=-32t^2 + 20t + 300. What the hell are they teaching kids these days?

It turns out that I am an idiot. It would seem that the equation in question is (g/2)*t^2 + vt + h. This is why I am not an engineer.

So i was wrong. And this professor IS a racist.
