1. Two vehicles A and B are traveling west and south, respectively, toward the same intersection where they collide and lock together. Before the collision A (total weight 1100 N) is moving with a speed of 73 m/s and B (total weight 1330 N ) has a speed of 51 m/s. Find the magnitude of the velocity of the interlocked vehicles after the collision.
2. What is the direction of motion of the interlocked vehicles after the collision? Give your answer in terms of the angle that the velocity vector makes with respect to East. (East = 0o, North = 90o, West = 180o, and South = 270o)
