Use the graph to determine the velocity of the object.
What is the instantaneous velocity of the object at 3 seconds?
⇒ 3 m/s
What is the average velocity of the object?
⇒ 0 m/s
The velocity of an object is the rate of distance over time.
Instantaneous Velocity
To calculate the instantaneous velocity at 3 seconds, we simply consider the distance of the object at 3 seconds.
From the graph, see attachment
[tex]d = 240m[/tex]
So, the instantaneous velocity (v) is:
[tex]v =\frac{d}{t}[/tex]
[tex]v =\frac{240m}{3s}[/tex]
[tex]v =80m/s[/tex]
Hence, the instantaneous velocity at 3 seconds is 80m/s
Average Velocity
To calculate the average velocity, we consider the total distance and the total time spent.
From the graph,
[tex]d = 480m[/tex]
[tex]t=6s[/tex]
So, the average velocity (v) is:
[tex]v =\frac{d}{t}[/tex]
[tex]v =\frac{480m}{6s}[/tex]
[tex]v =80m/s[/tex]
Hence, the average velocity is 80m/s
