Slide question #22 asks for velocity and all of the answer choices have acceleration units.
Thanks for pointing that out - the correction is made and posted.
The pdf is missing arrowheads and dots.
Create it with a free pdf print driver (Foxit Reader is good), and it will display correctly.
Matthew - thank you for alerting us to this issue. Our website actually converts the SMART Notebook presentation to PDF and it doesn't bring over the arrow heads. I have corrected the issue by taking a screen shot of the images with arrows - now the PDF has them. - Melissa
