Concept explainers
As a car accelerates, it does not accelerate at a constant rate; rather, the acceleration is variable. For the following exercises, use the 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 |
251. [T] Using your velocity equation from the previous exercise, find the corresponding distance equation, assuming your initial distance is 0 mi. How far did you travel while you accelerated your car? (Hint: You will need to convert time units.)
