Homework Help: Question about 1D motion

  1. Sep 13, 2004 #1
    The question goes as follows:

    A truck covers 40.0 m in 8.50 s while smoothly slowing down to final speed +2.40 m/s.

    Find the original speed

    Find the acceleration

    Now, I tried a couple things for the speed, I tried 40/8.50, and I tried (4.71/2.40) and both turned out to be wrong. Not sure of how to get the speed, couldn't get acceleration either.

    This problem is from Serway and Beichner Physics book, and i recall it's with constant acceleration, just use the kinematic equations..
