Homework Help: Rocket Height as one-dimension motion

  1. Sep 15, 2005 #1
    A rocket, initially at rest on the ground, accelerates straight upward from rest with constant net acceleration a, until time t1, when the fuel is exhausted.

    Find the maximum height H that the rocket reaches (neglecting air resistance).

    Express the maximum height in terms of a, t1, and/or g. Note that in this problem, g is a positive number equal to the magnitude of the acceleration due to gravity.

    That's part 1. Then comes:

    If the rocket's net acceleration is a=3g for t1=5.00 s, what is the maximum height the rocket will reach? (Using 9.81 m/s^2 for g).
