Simple question in Aerodynamic

  1. Oct 5, 2013 #1
    Hello every one:smile:

    I hope you can answer me when you read my question which is:

    If a plane in state of motion with three forces acting on it:1-Weight,2-Purpolsive(engine thrust),3-Aerodynamic(air Pressure)
    All three forces' vectors with the vector of motion are given.

    How can we guess the motion vector after a short time?

    Note"There is no more info beside what mentioned"

    THANK YOU SO MUCH:smile:

    The sum of the three force vectors results in a net force vector. The net force vector divided by the mass of the plane is the net acceleration vector, which can then be multiplied by a small amount of time to determine the change in the net velocity vector.
