Graphs of Motion

If the velocity-time graph has the shape AMB, what would be the shape of the corresponding acceleration-time graph?

Show answer and solution

Answer: (c)

$a$ = slope of the $v$ - $t$ graph.
A to M: straight line with negative slope, so $a$ is a negative constant.
M to B: straight line with positive slope, so $a$ is a positive constant.
So $a$ - $t$ is a negative step that jumps to a positive step at M. So the answer is (c).
