Homework Help: Formula Please!

  1. Nov 26, 2006 #1
    was wondering which formula I would use to solve this equation....

    a car traveling in a straight line has a velocity of +5.0m/s at some instant.
    After 4.0seconds, it velocity is +8.0m/s. What is it average acceleration in this time interval?
