12-224 (modified) At the instant shown, car A travels along the straight portion of the road with a speed of 25 m/s. At this same instant car B travels along the circular portion of the road with a speed of 15 m/s. Determine the velocity of car B relative to car A. B. Sketch the velocity vector from your answer C. Visualize and explain what the velocity of car B relative to car A would look like if you were sitting in Car A. D. If car A is slowing down at 2 m/s² and car B is moving at a constant velocity, what is the acceleration vector of car B relative to car A in horizontal and vertical components. To help clarify the geometry: Car A lies on line AC which is 30° from horizontal. Car B is only 15 degrees from horizontal (as its half-way around a 30° curve) Ans: A. VB/A=< -7.162, 8.618 > m/s D. ab/A=< 2.023, 0.087 > m/s² UND ما 15° p = 200 m 30° B -15°
