Homework Help: A rocket moves upward, starting from rest.

  1. Oct 25, 2009 #1
    1. The problem statement, all variables and given/known data

    A rocket moves upward, starting from rest with an acceleration of 32.2 m/s2 for 5.84 s. It runs out of fuel at the end of the 5.84 s but does not stop. How high does it rise above the ground?

    2. Relevant equations

    I do not know. All equations I have tried have been missing a variable.

    3. The attempt at a solution

    I tried finding the velocity and then adding it to what I got when plugging it into xf=xi+vi x t + 1/2g x t^2

    Break the motion of the rocket into two parts. Yes, you need to find the velocity the rocket is at after 5.84 seconds. Then you can use this information in the second stage of its motion.

    Show your calculations, so we can see what you are getting.
