When I integrate A= 3i , I will get 3ti + constant and B= vj so that it will be vtj + constant. I added the t because, the answer has to be with respect to time. And then I let it equal to -9i+6j= -3ti +vtj
So you mean that relative position is basically + vtj -3ti because its B relative to...
1.Two particles A and B have velocities 3i and vj respectively (in m/s).
(a) Find the position of B relative to A for all t given that r (b relative to a)
(t=0) = -9i+6j (in metres).
(b) Find the value of v such that A and B collide.
(c) If v=1 m/s, find the time and distance when A and B are...
