Which graph shows an object with constant acceleration?


A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 10, and velocity in meters per second on the y axis, numbered 0 to 50. A line starts at the origin and goes to (4, 40), then a line from (4, 40) to (9, 40) and a line from (9, 40) to (10, 0).
A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 5, and velocity in meters per second on the y axis, numbered 0 to 10. A line starts at (0, 10) and ends at (5, 0).
A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 5, velocity in meters per second on the y axis, numbered 0 to 35. A curved line starts at the origin and arcs up to (4.3, 35).

The second graph.

Reason: acceleration is the slope of a velocity vs. time graph. The second graph is a straight line (velocity decreases linearly from 10 m/s to 0 m/s in 5 s), so the slope (acceleration) is constant: a = (0 − 10)/(5 − 0) = −2 m/s².

The first graph is piecewise linear (different slopes in different intervals), and the third is curved, so their accelerations are not constant.
