Imagine (if you will) that this is an acceleration-time plot of a hummingbird that starts from rest and, oddly enough, moves only in one dimension. Draw a velocity-time plot that corresponds to this acceleration-time plot.

Based on this information, the hummingbird's final velocity is
A. Zero    B. Positive    C. Negative    D. Cannot be determined    E. Magenta   

Based on this information, does the bird ever move at constant velocity?
A. Yes    B. No    C. Cannot be determined   

Now suppose that the silly bird starts from the origin (X=0) and draw a position-time plot corresponding to the two previous plots.
