At the instant shown, the train on the straight track is traveling at a speed of 20 ft/s and is increasing its speed at 4 ft/s². At the same instant, the train on the circular track is traveling at 50 ft/s and is decreasing its speed at 2 ft/s². Determine the relative velocity and relative acceleration of car B with respect to car A at this instant. Express the answers as Cartesian vectors. O 500 ft 50 ft/s x 20 ft/s
