At one instant ,ships X and y are at a distance of d from each other.THe velocities of ship x and ship y are u and v respectively. Angle a and b are acute. Find the tangent of angle betweeen the direction of relative velocity and \(\displaystyle \vec{xy}\)javascript:;
My work:
the relative velocity vector is
xVy=VxVy=(u+vsin(a+b))i+(v cosb)j
relative displacement vector, xRy=(d)i
Before i proceed with the dot product formulas, can i confirm whether the above is crrect?
