At the instant shown car A is travelling with a velocity of 24 m/s and which is decreasing at 4 m/s2 along the highway. At the same instant B is travelling on the trumpet interchange curve with a speed of 20 m/s, which is decreasing at 5 m/s2. Determine the relative velocity and relative acceleration of A with respect to B at this instant.
