2. Sketching Acceleration vs time Graphs: Suppose the car shown in the sketch can move back and forth in a straight line. Assume the positive direction is to the right. Now sketch the Motion diagram (MD), change in velocity diagram using tail - to - tail method ( delta v), and acceleration vs time graph for the following cases and explain briefly why it make sense. a) (15 points) The car moves to the left from b) (15 points) The car moves from far left to the origin, speeding up at steady (constant) rate. right, slowing down at steady rate. MD: MD: Delta v. Delta v: Graph: Graph: Explanation: Explanation
