Is it possible? (Kinematics)

  1. Sep 2, 2012 #1
    Is it possible for velocity to be negative while the acceleration is positive? If so, then how is it possible?

    If you are rolling backwards in a car and put your foot on the gas pedal, you'll start accelerating forward instantly but until you come to a stop and start moving forward you'll have a negative velocity.

    Sounds like a homework question...

    Any object that has a negative velocity that is slowing down has a positive acceleration.
