Question:

At the instant shown car A is traveling with a velocity of 30 m/s and has an acceleration of 2 m/s² along the highway. At the same instant B is traveling on the trumpet interchange curve with a speed of 15 m/s, which is decreasing at 0.8 m/s². Determine the relative velocity and relative acceleration of B with respect to A at this instant.
