V 0 C. A V t B 2. Two identical objects, A and B, move along straight, parallel, horizontal tracks. The graph above represents the velocity as a function of time for the two objects. a. At approximately which time or times, if any, are the objects moving at the same speed? If the objects are never moving with the same speed during the interval shown, indicate this explicitly. Briefly explain your answer. b. At approximately which time or times, if any, are the objects moving with the same acceleration? If the objects are never moving with the same acceleration during the interval shown, indicate this explicitly. Briefly explain your answer. At approximately which time intervals is object B moving at a greater speed than A? If the object B are never moving with the same speed during the interval shown, indicate this explicitly. Briefly explain your answer.
