Rocket Launch question

  1. May 29, 2010 #1
    1. The problem statement, all variables and given/known data
    A rocket of mass 0.5kg is shot vertically and burns for 1.5s, providing a constant force of 22N.

    After 1.5s what is the height of the rocket above the ground?

    3. The attempt at a solution

    by taking m*g of the rocket (downwards force) away from the 22N force (upwards).
    I figured the resulting upwards force = 17N

    unsure how i use this to get the maximum height though

    Start with a free body diagram. What are the forces acting on the body? What is the resultant of these forces?
