Question

question 8 (1 point) calculate the average velocity from the table below. time (s) position (m) 0 0 1 2 2 4 3 6 a 8 m/s b 6 m/s c 3 m/s d 2 m/s

Explanation:

Step1: Recall average - velocity formula

The formula for average velocity $v_{avg}=\frac{\Delta x}{\Delta t}$, where $\Delta x$ is the change in position and $\Delta t$ is the change in time.

Step2: Determine $\Delta x$ and $\Delta t$

From the table, the initial time $t_1 = 0\ s$ and initial position $x_1=0\ m$, the final time $t_2 = 3\ s$ and final position $x_2 = 6\ m$. So, $\Delta x=x_2 - x_1=6 - 0=6\ m$ and $\Delta t=t_2 - t_1=3 - 0 = 3\ s$.

Step3: Calculate average velocity

$v_{avg}=\frac{\Delta x}{\Delta t}=\frac{6}{3}=2\ m/s$.

Answer:

D. 2 m/s
