The image above shows the graph of distance, first time (distance on the vertical axis, and the time on the horizontal axis) for a particular object. For reference, the object is at a position negative 4M when the time is 0 s and the position 5 AM when the time is 3 s. A. What is the acceleration of the object?B. What is the velocity of the object? C. On which time interval is the position of the object negative ?D on which time interval is the position of the object positive ??
