sorry the image is rather small. It shows the velocity of an object between time 0 and 9.
-When does the object obtain its greatest speed? I think it obtains its greatest speed at t=8, since time vs. velocity shows acceleration. Is this right
-The object was at its origin at t=3. When does it return to its origin? I thought it returned at t=6, but I got this problem wrong. Can someone guide me in the right direction because I have no clue!
