[T] Suppose you go on a road trip and record your
speed at every half hour, as compiled in the following table. The best quadratic fit to the data is
graph.
Time(hr) | Speed (mph) |
0 (start) | 50 |
1 | 40 |
2 | 50 |
3 | 60 |
As a car accelerates, it does not accelerate at a constant rate; rather, the acceleration is variable. For the following exercises, use die following table, which contains the acceleration measured at every second as a driver merges onto a freeway.
Time(sec) | Acceleration (mph/sec) |
1 | 11.2 |
2 | 10.6 |
3 | 8.1 |
4 | 5.4 |
5 | 0 |
