pdf slides 8, 13, 71 are cut off.
Vectors in slides 107 and forward have no arrowheads

Matthew - I just reposted a new version - I can't get slides 8 and 13 to not cut off some of the words, but I did fix all of the missing arrowheads from slide 107 and on. - Melissa

Multiple choice question #20 has several correct answers.
Since the problem gives the angle, A is also correct with a little trig.
Just delete the first sentence about the angle.

Matthew, you're absolutely correct.  I'll delete the first sentence - will do this tomorrow so I can re record it.  Thanks,  John

Recorded, new version posted, recording arriving soon.
