Assuming you have the same version, the answer to #9 from Mazur's book is #5"John Clement" <clement@hal-pc.org> 2/13/2009 2:14 pm >>>
I'm trying to avoid "spoiling" the FCI answers, but I'd like some opinions
on one of the questions and whether it should be included. Can we do that
here?
I'm NOT INTERESTED in opinions on the FCI in general, just on question #9.
I don't have the "official" answer sheet, but I'm not sure whether the
intent is to test vector addition or relative direction of acceleration
and velocity. One would expect different answers depending on the concept
being tested. The first time I read the test, I said "Oh, this is vector
addition." But a closer look makes me think of "instantaneous"
perpendicular impulse.
What do you think is intended?
Bill
