1-D Kinematics Problems 1. Answer the following based on the velocity vs. time graph. x (m) N (m/s) 0 (s) -8t (s) do a. Give a written description of the motion. b. Determine the displacement from t = 0s to t = 4 s. c. Determine the displacement from t = 2 s to t = 6 s. d. Determine the object's acceleration at t =4s. e. Sketch a possible x-t graph for the motion of the object. Label the axis. Explain why your graph is only one of many possible graphs. 2. Answer the following based on the position vs. X time graph. a. Where on the graph above is the object moving C most slowly? (How do you know?) D b. Between which points is the object speeding up? G (How do you know?) c. Between which points is the object slowing down? (How do you know?)
