A Train goes between three stops A,B,C in that order. From A to B the train travels 75 kilometer south and between B and C it travels 100 kilometer northwest.
(a) Show the locations of A,B, and C on the graph with clearly labeled and scaled xy coordinates.
(b) Find the components of the train's displacement between A and C.
(c) Evaluate the magnitude and direction of the displacement?
