Homework Help: A race car traveling at +44 m/s

  1. Oct 7, 2003 #1
    A race car traveling at +44 m/s is uniformly accelerated to a velocity of +22 m/s over an 11-s interval. What is the displacement during this time?

    (Don't solve it)

    Why is the car being accelerated from +44 m/s to +22 m/s . . . wouldn't it be deacceleration?

    figured it out

    heh, deacceleration is acceleration just in the opposite direction; therefore, deacceleration can be positive or negative.

    Thanks Royhaas!
