At t = 0, v1 makes an angle theta 1 with the line joining A and B and v2 makes an angle theta 2 with the line joining A and B. (a) Find the condition for A and B to collide. (b) Find the time after which A and B will collide if separation between them is d at t = 0.

Two particles A and B are moving with constant velocities v 1 and v 2 . At t = 0 Two particles A and B are moving with constant velocities v_1 and v_2. At t = 0 v 1 ​ makes an angle θ 1 ​ with the line joining A and B and v 2 ​ makes an angle θ 2 ​ with the line joining A and B. Find their velocity of approach.
