B1-QRT51: VELOCITY-TIME GRAPHS-DIRECTION The graphs below show the velocity versus time for boats traveling along a straight, narrow channel. The scales on both axes are the same for all of these graphs, and the boats all start at the same origin. In each graph, a point is marked with a dot. $\mathbf{B}$ C D F Indicate in the chart below if the position, velocity, and acceleration directions of the boat at the points indicated are in the positive (+), negative $(?)$, or no direction (0) Explain your reasoning.
