```										eq of path of projectile is s=ucos@ -gt2/2
if two projectiles are projected from horizontal ground with different initial velocity and angle....both these quantities are known then at any time t
coordinates of A,  S1=(UacosA)t i - gt2/2 j
coordinates of B, S2=(UbcosB)t i - gt2/2j
coordinates of A wrt to B is S2-S1=t(UacosA-UbcosB)i + 0 j
Xi + Yj = kt i + 0j                                     (UacosA-UbcosB = constant=k)
ie X=kt  is a straight line
