Rocket trajectory in vertical launch then free fall

  1. Jun 9, 2009 #1
    1. The problem statement, all variables and given/known data
    A rocket is launched to travel vertically upward with a constant velocity of say...20 m/s.After
    travelling maybe 35 s the rocket develops snag and its fuel supply is cut off. the rocket then travels like a free body, the height achieved by the rocket will be



    2. Relevant equations
    displacement=velocity *time

    3. The attempt at a solution
    20 *35=700m

    this is not the answer why?

    Re: rocket

    you add to that the extra displacement the rocket travels as a free body till the point where its velocity reachs [0 m/s]
