Answer:
Let vr-> be the reltive velocity between two projectiles
|(vr)x|=(v1+v2)cos60 degree =(8+16)*0.5=12
|(vr)x|=(v1+v2)sin60 degree=(16-8)*root3/3=root4*3
therefore vr=root{|(vr)x|^2+|(vr)x|^2}=root{12^2+root4*3}=root{192}
vr*10root3=8root3*10root3=240
distance between A and B AB=root{(240)^2+70^2=250m
