Textbook Question
Chapter 5, Problem 4Q
What would be the shapes of the curves for a graph of y versus t of the data in each experimental case? How would you determine the value of the car’s acceleration from a graph using only y and t values (that is, not computing vi)?

please help with the two boxes that i have circled with a green color based on my data! g=9.8 m/s is the accepted value and the equation g= 4 pie etc whatever that equation is, is the measured value to find the percentage error! and please then answer the three questions on the bottom
At 9:13 A.M., a sports car is traveling 30 miles per hour. Two minutes later, the car is traveling 90 miles per hour. The mean value theorem guarantees that at some time during this two-minute interval, the car's
acceleration is exactly A miles per hour squared. Compute the value of A.
A =
mi/h²

In physics labs, explain why we insist on getting our final results from the slope of a graph, rather than simply averaging a list of values. Be as specific as possible.
