19. Speed of a car The accompanying figure shows the time-to- distance graph for a sports car accelerating from a standstill. P 650 600 Q4 Q3 500 400 Q2 300 200 100 5 10 15 20 Elapsed time (sec) a. Estimate the slopes of secant lines PQ¡, PQ2, PQ3, and PQ4, arranging them in order in a table like the one in Figure 2.6. What are the appropriate units for these slopes? b. Then estimate the car's speed at time t = 20sec. Distance (m)
