Movement of 2 particles Described by vectors

  1. Dec 1, 2012 #1
    We have 2 particles A and B - velocity vectors: v(A)=(2; 0), v(B)=(0; 3).
    In time t=0 these particles were in r(A)=(-3; 0), r(B)=(0. -3) (both are also vectors)
    Determine a vector of the reciprocal position of A and B (means the position of one relative to the other). Compute time and lenght of maximal reprochement of A and B.



    We work with vectors, so for better understanding i tried to put them into x-y coordinate system but a came across a problem with direction of v(A) and v(B). So I cant imagine the whole situation. I think next step will be to write r(A), r(B) as r(t), t=time

    Does that mean the position of one relative to the other?
    Please post your attempt at solution. (See forum rules.)

    Yes, that would be a good move. For clarity, use rA(t), rB(t). Then you can also write down rB-A(t)
