#### Problem 1
The position of an object is given as a function of time as \( x(t) = (3.0 \, \text{m/s})t + (2.0 \, \text{m/s}^2)t^2 \).
**What is the average velocity of the object between \( t = 0.0 \, s \) and \( t = 2.0 \, s \)?**
---
**Solution:**
1. First, find the position of the object at \( t = 0.0 \, s \):
\[
x(0) = (3.0 \, \text{m/s})(0) + (2.0 \, \text{m/s}^2)(0)^2 = 0 \, \text{m}
\]
2. Next, find the position of the object at \( t = 2.0 \, s \):
\[
x(2) = (3.0 \, \text{m/s})(2) + (2.0 \, \text{m/s}^2)(2)^2
\]
\[
x(2) = (3.0 \, \text{m/s})(2) + (2.0 \, \text{m/s}^2)(4)
\]
\[
x(2) = 6.0 \, \text{m} + 8.0 \, \text{m} = 14.0 \, \text{m}
\]
3. The average velocity (\( \overline{v} \)) between \( t = 0.0 \, s \) and \( t = 2.0 \, s \) is given by the change in position divided by the change in time:
\[
\overline{v} = \frac{x(2) - x(0)}{2.0 \, \text{s} - 0.0 \, \text{s}}
\]
\[
\overline{v} = \frac{14.0 \, \text{m} - 0.0 \, \text{m}}{2.0 \, \text{s}}
\]
\[
\overline{v} = \](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F018a4c08-f0b7-420b-9137-49c7ccffa10b%2Febd81cdc-6768-457f-a4da-dd1f57e6bfa8%2F14r6qhp_processed.png&w=3840&q=75)
