Question

2.50 2.00 1.50 Distance (meters) 1.00 0.50 0.00 0.00 0.10 0.20 0.30 0.40 0.50 0.60 0.70 0.80 Time (sec) A continuous stream of data for this experiment would look like the graph above. Using a ruler, draw a chord from the origin to the point (0.60, 1.80). Then, draw another line that is tangent to the curve and parallel to the chord you just drew 5) 6) What is the time coordinate of the point where this tangent line touches the curve? 7) What relationship do you notice between the time coordinate of the tangent point and its corresponding time interval, Ar? This will only be apparent if the lines have been drawn carefully 8) In Calculus, what is the name of the slope of line drawn tangent to a curve (when the curve is a graph of given function)? What is the name of the physical quantity given to the slope of a line tangent to a distance vs. time curve? Since the chord is parallel to the tangent line, their slopes are equal. Assume your result from exercise (7) is generally applicable. Complete the following expression to obtain a general conclusion about when the average speed equals the object's instantaneous speed. 9) 3 2

i need question 7 and 9 done immediately
Thank you very much
