    How Do Velocities Affect Collision and Proximity in Particle Dynamics?

    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...

    Yes, that is the way the problem is stated. So the relative position is vj-3i ?

    How Do Velocities Affect Collision and Proximity in Particle Dynamics?

    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...
