A lab cart moves along a straight horizontal track. The graph describes the relationship between the velocity and time of the cart. A student reasons that the cart moves a greater distance from 0-4 s than it does from 16-20 s because the cart's displacement during the interval from 16-20 s is negative. a. Which aspects of the student's reasoning, if any, are correct? Explain how you arrived at your answer.
b. Which aspects of the student's reasoning, if any, are incorrect? Explain how you arrived at your answer
c. Describe how the graph could be used to find the acceleration at t = 9s.
d. Sketch an acceleration-time graph of the cart from t= Os to t= 20 s. Clearly label the axes and include appropriate units.
e. Describe how the velocity-time graph could be used to determine the position of the cart over time. Assume the car starts at x = Om at t= Os.
f. Sketch a position-time graph of the cart from t= Os tot= 20 s. Clearly läbel the axes and include appropriate units.
