Question

calculating velocity
use the graph to determine the objects average velocity. what is the average velocity of the object?
m/s
position vs time

Explanation:

Step1: Identify two points on the graph

Let's take the points \((t_1 = 0\ s, x_1=0\ m)\) and \((t_2 = 50\ s, x_2=- 30\ m)\)

Step2: Use the formula for average velocity

The formula for average velocity is \(v_{avg}=\frac{\Delta x}{\Delta t}=\frac{x_2 - x_1}{t_2 - t_1}\)
Substitute the values: \(v_{avg}=\frac{-30 - 0}{50 - 0}\)
\(v_{avg}=\frac{-30}{50}=- 0.6\ m/s\)

Answer:

\(-0.6\ m/s\)
