Please answer and include explanation

Question 8 (1 point) Assume two cars start from rest and simultaneously begin to move with the same acceleration. Throughout the motion, the relative velocity of one w.r.t. other is O directed perpendicular to the acceleration 0 zero 0 not enough information Q non-zero and directed opposite to acceleration O non-zero and directed parallel to acceleration Question 7 (2 points) What should be the minimum velocity for a 5.2-kg box at state B to not loose the contact with the top of the loop? Assume r 20.6 m. The input field requires answers with 3 significant figures and abbreviated units (e.g., seconds = 5, meters = m). Your Answer: Answer units
