Collision at an Angle
To apply conservation of linear momentum in an inelastic collision. Two cars, both of mass m, collide and stick together. Prior to the collision, one car had been traveling north at a speed 2v, while the second was traveling in a southeastern direction at an angle ϕ with respect to the east-west direction and at a speed v. After the collision, the two-car system travels in a northeastern direction at an angle θ with respect to the north-south direction and at a speed v final.
What is the angle θ (with respect to north) made by the velocity vector of the two cars after the collision?
Express your answer in terms of ϕ. Your answer should contain an inverse trigonometric function.
