  1. Oct 22, 2012 #1
    I have no clue where to begin with these assignments, can anyone walk through the steps to these?

    1. An automobile accelerates from rest at
    1.7 m/s2 for 22 s. The speed is then held
    constant for 29 s, after which there is an ac-
    celeration of −5.8 m/s2 until the automobile
    What total distance was traveled?
    Answer in units of km

    2. A speedboat increases in speed from 19.3 m/s
    to 34.2 m/s in a distance 202 m.
    Find the magnitude of its acceleration.
    Answer in units of m/

    At least give us the variables in symbol form. You've got to show some effort.
