Question

Two particles A and B have velocities 3^i and v^j respectively (in m/s).
(a) Find rBjA; the position of B relative to A for all t given that
rBjA(t = 0) = 9^i + 6^j (in metres).
(b) Find the value of v such that A and B collide.
(c) If v = 1 m/s, nd the time and distance when A and B are closest together.
