Velocity and Acceleration Graphing Activity. *Note: In this activity, X means position or change in displacement!!! (meters) v = velocity (m/s), and t = time (s) All calculated acceleration values will be in units of m/s 2. 1.) X = 3(t-2) 2 + 3 from t= 1 to t= 3

1.) X = 3(t-2)2 + 3 from t= 1 to t= 3 • A.) Sketch the graph. What units are X? What units are t? • B.) Label the t values which have the greatest positive and negative slope. • C.) Calculate the slope at each—with the correct units!!! • D.) Explain what is happening at the two points you mentioned in B. • E.) Is there any time(s) where the slope is 0? Where is it? What is happening here?
