Homework Help: Acceleration/velocity opposite signs

  1. Sep 2, 2007 #1
    1. How do I draw a v-t graph to prove a scenerio where velocity and acceleration have opposite signs?

    2. I know that by having opposite signs, it shows that the object is slowing down

    3. Would it be a line with a negative slope? (thinking that the graph is just showing the quadrant I)

    That would be one example (where the velocity is positive--above the x-axis--while slope is negative). You can also do the opposite.
