How do you calculate deceleration due to resistance?

  1. Feb 15, 2009 #1
    I have a rocket with a top velocity of 14.16 m/s when the engine stops.

    How do i calculate its deceleration based on air resistance and gravity if it is flying at approximatly 45 degress?

    There is no easy way to deal with air resistance. It is ignored in most courses.
    Also, we usually simplify matters by saying the engine burns for so small a time it is effectively zero.

    So, it is just another baseball problem. Do the horizontal and vertical parts separately.
