Two cars, both of mass , collide and stick together. Prior to the collision, one car had been traveling north at speed , while the second was traveling at speed at an angle south of east (as indicated in the figure). After the collision, the two-car system travels at speed at an angle east of north.(adsbygoogle = window.adsbygoogle || []).push({});

What is the angle with respect to north made by the velocity vector of the two cars after the collision?

Express your answer in terms of . Your answer should contain an inverse trigonometric function.

I have already tried tan(theta)=cos(phi)/(2-sin(phi)) and arctan(cos(phi)/(2-sin(phi)) and tan(cos(phi)/(2-sin(phi)) but none seem to be the right answer

someone help please!
