If an object increases velocity at a uniform rate from 5 m/s to 21 m/s in 12 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 5 m/s and whose velocity 12 seconds later is 21 m/s. Explain what the slope of the graph means and why, and also what the area means and why.

Acceleration: 21m/s-5m/s=16m/s/12s=(4/3m)/s/s

The slope is the velocity because rise/run is acceleration over time. The area is the distance traveled because the 1/2h*l is 1/2 change in velocity*change in time."

&#This looks very good. Let me know if you have any questions. &#
