Homework Help: Velocity and Acceleration - Verbal Response

  1. Sep 1, 2008 #1
    1. The problem statement, all variables and given/known data
    An automobile is traveling west. Can it have a velocity toward the west and at the same time have an acceleration toward the east? Under what circumstances.

    3. The attempt at a solution
    I wrote "Yes, the car can be moving west and speeding up with a positive velocity (assuming west is the positive x-axis) and at the same time having a negative acceleration towards the east."

    Does my response answer the question? I am having a hard time with this. Can anyone assist me or guide me in the right direction?

    Thanks beforehand.

    You seem to have the correct grasp on velocity and acceleration. I would just be careful about using the wording "speeding up," as it seems to imply changing/increasing velocity when really in your case the car is slowing down, as it has an acceleration to the east
