Math Problem Statement
Solution
The problem is asking to calculate average velocities over different time intervals for a given position function , and then make a conjecture about the instantaneous velocity at .
Steps to solve:
-
Average velocity formula: The average velocity over a time interval is given by: Here, and takes different values like 4, 3.1, 3.01, etc.
-
Position function evaluation: You'll need to plug in and into the position function for each interval.
I'll compute the values for you. Let's start with the first interval and work through each interval step by step.Here are the calculated average velocities for each time interval:
- For the interval , the average velocity is approximately .
- For the interval , the average velocity is approximately .
- For the interval , the average velocity is approximately .
- For the interval , the average velocity is approximately .
- For the interval , the average velocity is approximately .
Conjecture:
As the time intervals become smaller and closer to , the average velocity approaches approximately . Therefore, the instantaneous velocity at is likely around .

Here are 5 follow-up questions to deepen your understanding:
- How do we compute instantaneous velocity from a position function?
- Why does the average velocity approach a specific value as the time interval shrinks?
- Can we find the exact instantaneous velocity at using differentiation?
- How would the velocity change if the position function had a different quadratic coefficient?
- What happens to the average velocity if we extend the time intervals instead of shrinking them?
Tip: The instantaneous velocity is the derivative of the position function at a specific time.
