    are there any notes on reltive velocity(including these i and j questions)? because it was not in the add maths book..

    ohh got it. i thought true velocity means the velocity in still air.

    V(p)= true velocity of plane V(p/w)=velocity of p relative to w this is in the book

    Maths, Addmaths and Statistics: Post your doubts here!

    isn't V(p) the velocity in still air in the formula?
