If an object increases velocity at a uniform rate from 6 m/s to 26 m/s in 10 seconds, what is its acceleration and how far does it travel?Sketch a velocity vs. clock time graph for an object whose initial velocity is 6 m/s and whose velocity 10 seconds later is 26 m/s. Explain what the slope of the graph means and why, and also what the area means and why.
The acceleration would be 2 m/s^2. The average velocity would be 13 m/s. The slope of the graph represents the change in velocity. The area represents the total displacement.
You don't say how far the object traveled.
13 m/s is half the final velocity, but in this case that is not the average velocity.
