Question

velocity vs time
based on the graph of velocity over time, which could be the initial velocity and the final velocity for this graph?
initial = 0 m/s; final = 2.5 m/s
initial = 2.5 m/s; final = 2.5 m/s
initial = 3.0 m/s; final = 6.0 m/s
initial = 6.0m/s; final = 3.0 m/s

Explanation:

Step1: Understand velocity - time graph

In a velocity - time graph, the initial velocity is the velocity at the start (time = 0) and the final velocity is the velocity at the end - point of the time interval considered. For a horizontal line on a velocity - time graph, the velocity is constant over time.

Step2: Analyze the graph

The given velocity - time graph is a horizontal line. This means the velocity does not change with time. So, the initial velocity and the final velocity are the same.

Answer:

Initial = 2.5 m/s; final = 2.5 m/s
