It details the sprinter's acceleration for 4 seconds, a constant speed for 3 seconds, and subsequent deceleration. The graph's slope indicates changing acceleration: an upward slope for acceleration, a flat line for constant speed, and a downward slope for deceleration. Additionally, it notes a comparison with another sprinter who achieves a higher speed in the same period.
The changing velocity of the sprinter—or of any other moving person or object—can be represented by a velocity-time graph like the one in the Figure below for the sprinter. The sprinter’s velocity inc...The changing velocity of the sprinter—or of any other moving person or object—can be represented by a velocity-time graph like the one in the Figure below for the sprinter. The sprinter’s velocity increases for the first 4 seconds of the race, it remains constant for the next 3 seconds, and it decreases during the last 3 seconds after she crosses the finish line.
