Predict and sketch the appearance of the displacement vs time graph, velocity vs time graph, and acceleration vs time graph a person moving towards the positive {+1 x-direction with a constant velocity 'om a chosen starting point for a period of It} seconds. Predict and sketch the appearance of the displacement vs time graph, velocity vs time graph, and acceleration vs time graph a person moving towards the negative {-} x-direction with a constant velocity from a chosen starting point for a period of It} seconds. . Predict and sketch the appearance of the displacement vs time graph, velocity vs time graph, and acceleration vs time graph a person moving towards the positive (+] rut-direction with increasing speed velocity from a chosen starting point for a period of It} seconds. Open the PhET Interactive Simulations The Moving Man and click \"Charts\". You will see 3 graphs: displacement versus time graph, velocity vs time graph, and acceleration vs time graph. . Using the PhET Interactive Simulations The Moving Man, produce the motion graphs describing step 1to 3. Take a screenshot or print these graphs and put it side by side with your predicted swabs- Activity 2: Graph Matching 1. Open the PhET Interactive Simulations - The Moving Man and click "Charts". Move in such a way that the graph of the man's motion matches the displacement versus time graph below (Figure 1). Figure 1. Retrieved from https://www.gigaphysics.com/graphs_lab.html 2. Open the PhET Interactive Simulations - The Moving Man and click "Charts". Move in such a way that the graph of the man's motion matches the velocity versus time graph below (Figure 2). Figure 2.

Retrieved from https://www.gigaphysics.com/graphs lab.htmlActivity 3: Graphical Analysis of Motion 1. Walk in a straight line for 10s starting from rest. Mark and measure the distance you travelled every second. 2. Plot total displacement versus total time using Excel. Draw the best fit line or curve. 3. Determine the instantaneous velocity at the end of each time interval. Instantaneous velocity = 2 average velocity 4. Plot instantaneous velocity versus time. Draw the best fit line/curve. 5. Analyze your motion graphs. 9 Activity 4: Reaction Time 1. Ask a person to hold a ruler vertically at the 30-cm mark while you position your thumb and index finger (without touching the ruler) at the 0-cm mark. 2. Let the person drop the ruler without telling you. Catch it with your thumb and index finger. 3. If you catch the ruler, compute your reaction time from the formula t = where h (in meters) is the distance the ruler has fallen measured from the 0-cm mark to where you catch the ruler. 4. Repeat the procedure while being distracted (e.g talking to a friend using your cell phone). 5. Ask other people to do the activity (if available). Analyze the difference between with and without distraction of different people.Post Laboratory Questions 1. Devise a way to determine the height of a building using only a stopwatch. 2. From the point of view of physics, is there a basis to the law banning the use of cell phone while driving
