Draw the velocity graphs for an object whose motion produced the posi- tion-time graphs shown below on the left. Position is in meters (m) and ve- locity in meters per second (m/s). (Note: Unlike most real objects, you can assume that these objects can change velocity so quickly that it looks in- stantaneous with this time scale.)
