v Interpreting Your Graphs In this section, you will use your graphs to figure out key concepts. 1. Sketch a free-body diagram for the kickball immediately after it leaves the girl's hands. Assume there is no air resistance. Hint: You can click @ to add a picture to your answer. BIU EEEE Score: 0/1 2. Now think about the FBD of the kickball when it is at its highest point. What, if anything, should be different? Explain .Saved your reasoning. Hint: Remember a force is an interaction between two objects. What objects is the kickball interacting with when it leaves the girl's hands? What about when the kickball is at the top of its motion? The force gravity is interacting with the kickball when it leaves the girl's hands.3. Describe the horizontal motion of the kickball. Make sure you point out features of your graphs that support your answer. BIU FREE Score: 0/2 4. Is your description of the horizontal motion consistent with what you'd expect from the free-body diagram? Explain your reasoning. Hint: What does your FBD tell you about the horizontal forces acting on the kickball? BIU FEEE Score: 0/25. Describe the vertical motion of the kickball, Make sure you point out features of your graphs that support your answer. BIIJEEEEE'EE. Snore: 01"2 6. Is your description of the vertical motion consistent with what you'd expect from the free-body diagram? Explain your reasoning. Hint: What does your FED tel! you about the vertr'cai forces acting on the kickba? Btu iEEEEE \"bag Snore: on I". Find the vertical acceleration of the kickball. Explain how you fund your answer. Hint: How can you use the graphs you made earlier to nd acceleration? Bra 5525:: %EE Score: or 1 B. Is the value of the acceleration consistent with your i'neve-hodyI diagram? Explain your reasoning. BIUEEEEE oll Score: Oil .\\\\ 1. You will need to make a total of three different graphs: . Horizontal position vs. time . Vertical position vs. time . Vertical velocity vs. time Record your position and time data, then use the rate of change function to find the vertical velocity. Remember that as long as you have all of your data in the data table, you can easily switch between the three different graphs. Vertical Position Horizontal Position ...
