    1. The problem statement, all variables and given/known data

    A rocket moves upward, starting from rest with an acceleration of 29.0 m/s^2 for 8.00 s. It runs out of fuel at the end of the 8.00 s but does not stop. How high does it rise above the ground? (in meters)


    2. Relevant equations

    deltaX=(1/2)final velocity * change in time ???

    3. The attempt at a solution


    i really don't understand which of the equations of straight-line motion would be relevant, and how, for example: 29m/s^2 is DIFFERENT than just 29m/s

    Yes, 29.0 is the acceleration not velocity... what are your displacement equations for uniform acceleration?
