**Unformatted text preview: **figure between 35 s and 40 s the slope becomes zero at and the displacement is 20 m. Solution (d) Since the object's displacement started at zero went to 20 meters then to 10 meters it must of turned around. Or looking at the slope first its positive then negative so the velocity changed direction. http://www.hwproblems.com/cgi-bin/book.cgi?bookid=0044&cptn=2pr51&id=62762 [1/31/2008 12:16:39 PM]...
