A. why might a smart student say the object reverses direction?

B. why might a smart student say the object doesn't reverse direction?

C. Does the object reverse direction? Explain why.
Answered by drwls
Velocity reverses direction only if V goes from positive to negative, or negative to positive. Triangle-shaped V(t) graphs do not have to cross the x axis, but they might. Were you given a specific graph?
Answered by Andrea
yeah the graph they gave me was triangle shape was above the x-axis. the two ends of the legs are touching the x-axis but does not cross all the way to the negative side.
