If line with y=0 is moving with velocity vĴ and line y=x is moving with velocity (v/√2)*(i^ - Ĵ), then find speed of intersection point of two lines. ( here i^ means i cap and Ĵ means j cap)

if a(cap) and b(cap)are unit vectors at an angle theta show that |a(cap)-b(cap)=2(sin theta/2 )

a accelerated body covers distance a,b,c in time l,m,n show that a(m-n)+b(n-l)+c(l-m)=0
