Question1

Six vectors (A to F) have the magnitudes and directions. Part A ranks the vector combinations on the basis of their magnitude. Rank from largest to smallest. To rank items as equivalent, overlap them. (F+C), (D), (A+E), (A+C), (A+D), (A+B) Part B rank vector combinations on the basis of their angle, measured counter clockwise from the positive x axis. Vectors equivalent to the positive x axis have an angle of 0 degrees. All angle measures fall between 0 and 360 degrees. Rank from largest to smallest.

Question2

Two trains, each having a speed of 27 km/h, are headed at each other on the similar straight track. A bird that can fly 54 km/h flies off the front of one train while they are 54 km apart and heads straight for the other train. On reaching the other train it flies directly back to the first train, and so forth. (We have no idea why a bird would behave in this way.) What is total distance the bird travels by the trains collide?
