Question

in the following graph, what is the objects average velocity?
graph 1
5 m/s
18 m/s
10 m/s
12 m/s

Explanation:

Step1: Recall the formula for average velocity

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 graph

From the graph, at \(t = 0\ s\), \(x=0\ m\) and at \(t = 5\ s\), \(x = 50\ m\). So, \(\Delta x=x_{final}-x_{initial}=50 - 0=50\ m\) and \(\Delta t=t_{final}-t_{initial}=5 - 0 = 5\ s\).

Step3: Calculate the average velocity

Substitute the values into the formula: \(v_{avg}=\frac{50}{5}=10\ m/s\)

Answer:

10 m/s
