6. Sketch the velocity vs. time graphs and the motion maps corresponding to the written descriptions of
the motion of an object.
a. The object is moving in the positive direction at a constant (steady) speed.
b. The object is standing still.
c. The object moves in the negative direction at a steady speed for 4s, then stands still for 4s.
d. The object moves in the positive direction at a steady speed for 4s, reverses direction and moves back
toward the negative direction at the same speed.
