An object starts at position x = +10 meters. It moves at +5 m/s for 10 seconds then (instantly! magically!) changes its velocity to -10 m/s for the next 10 seconds. Draw a graph showing the object's position as a function of time.

Draw a graph showing the object's velocity as a function of time.

What is the object's displacement? Use a fact + connection to explain how you know the displacement.
