Relative Motion
Two particles leave the same point at time t=0, each one over a straight line with constant acceleration a. If Ө is the angle of the two lines, how varies the distance d between the particles with time?

Solution:
The particles leaves the same point O with uniform acceleration of magnitude a, along lines OA and OB
Initial velocity of both the particles is u ...
