1. Motion Diagrams and Graphs: There are two diagrams. One on the left is motion diagram of an object and the other one is graph paper with labelled axes. (a) (5 points) Complete the graph of the motion represented by the motion diagram. x (m) to the East 8 6 4 2 t (s) 1 2 3 4 5 0s East Motion Diagram of an object to east indicated by the little arrow. Time is measured in an interval of 1s starting from 0s. Plot the points and draw a smooth trend line (b) (5 points) In the completed graph of part (a), mark the position of the object at 1s and 2s and connet the position by straight line segment. Find the approximate slope of the segment. What physical quantity does this slope represent? (c) (5 points) In the completed graph of part (a), mark the position of the object at 3s and draw the tangent line at that point. Compute the slope of the tangent line. (d) (5 points) What is the direction of the velcity of the object near 1s ? Near 3s? Explain? Is the object slowing down or speeding up based on the graph? Explain

Step 1
However, based on the description, you would plot the position of the object at each second on the graph. The x-axis would represent time in seconds, and the y-axis would represent the position of the object in meters to the East. Show more…

Question 1: Which of the following graphs is traveling at a constant speed? Graph E Graph F Graph G Graph H Question 2: Which line represents the constant acceleration? A, B, and D A only C only B and D only Question 3: The following displacement graph was created from a toy cart's travel around a small track connected to a computer for data graphing. Which statement below is true based on the graph? Line segment AB is showing the cart traveling at 10 m/s. Line segment BC is showing acceleration as the cart is increasing its speed. Line segment DE is showing the cart is traveling at a constant rate. Line segment CD is showing acceleration as the line has a straight increasing slope. Question 4: Study the two graphs. Use your knowledge of speed and velocity to determine if they are representing the motion of the same object and why. No, the speed graph shows an object (1) at a steady speed, (2) slowing down, (3) stopping and rolling back. The velocity graph shows the object (1) speed up (2) slow down, and (3) stop completely. Yes, the object moves (1) at a steady rate (2) speeds up (3) stops and then rolls back, slowing down. Yes, the object moves (1) at a steady rate (2) slows down (3) stops and then rolls back, speeding up. No, the speed graph shows an object (1) speeding up and then (2) slowing down. The velocity graph shows the object in (1) constant motion and then (2) stopping.

Graphical Analysis of Motion: Refer to the graphs to answer the following questions (m/s) (m/s) 3.5 5.5 1.0 1.5 0.0 1.3 (s) 0.75 1.3 t (s) Calculate the displacement and acceleration for the motion described for each of the above graphs, respectively. An object is tossed vertically and its motion is plotted on the following graph. Answer the following questions using the graph: (m/s) 4.5 a. Calculate the object's acceleration. 1.1 t (s) At what time does the object reach its highest point? -5.5 Calculate the displacement for the object when it reaches its highest point. Find the total displacement for the object from t=0s to 1.1s. Then sketch the corresponding position-time graph.
