Death by Reentry

Chem-E I get, but it gets even weirder when they start abbreviating civil engineer as Dum-E.

Which one? The lack of a consistent coordinate system. Might be nit-picking as the teacher does add the values,but if you're teaching students you should be able to do this. The mysterious way the teacher has sin(30)=.78722. I can't even figure out how this error would occur. The way they are off an order of magnitude for the change in x velocity. They realize it at the end, but did not correct any of the previous steps to account for this.

You could always print off your teachers solution mark the mistakes and hand it back to him/her with a 3 out of 8. Not recommended, but the errors are pretty bad.
