Two particles A and B have velocities 3i and vj respectively (in m/s).
(a) Find rB|A, the position of B relative to A for all t given that rB|A(t = 0) = −9i+6j
(in meters).
(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 closest together.
