Motion Under Gravity

The following plots show variation of velocity $(v)$ with time $(t)$ of a ball thrown vertically upward, and falling back. Which of the following plots is/are correct?

Show answer and solution

Answer: (a)

Taking upward as positive, $v = u - gt$ : a straight line with constant negative slope $-g$ .
$v$ starts positive, becomes zero at the top, then becomes negative while falling, so the line crosses the $t$ -axis and continues below it: graph C.
A and E show speed (never negative), B rises then falls, D starts negative with positive slope, so none of these is correct.
So the answer is (a) C only.
