Question

A body is thrown vertically upwards. Which one of the following graphs correctly represent the velocity $v_s$. Time

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Velocity at any time $t$ is given by,
$v=u+at$
If we take upward direction as positive and downward direction as negative, we can write
$v=v_0+(-g)t$
$v=v_0-gt$
It represents a straight line with negative slope.

Final answer: (a).
