A runner is training for an upcoming marathon by running around a 112-m-diameter circular track at constant speed. Let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. The runner starts at (x, y) = (56 m, 0 m) and runs 2.5 times around the track in a clockwise direction. What is the magnitude of his displacement vector? ............. Whar is the direction of his displacement vector? West...
