Is this trend in agreement with the conclusion you drew from the velocity graph? Explain your answer. (2 points) Since this graph suggests a constant acceleration, the best estimate for the acceleration is obtained using an arithmetic average. Calculate the arithmetic average of all calculated accelerations and enter it below, together with units. (2 points} In this experiment you studied the motion of a puck that turned out to have constant acceleration. You determined experimentally the acceleration in three different ways: from the velocity graph, from the position graph, and from the acceleration data. As a conclusion, summarize: a) how each graph convinced you that the acceleration is constant, and b) how you determined the best estimate for the acceleration from each graph
