Question

A body is thrown vertically upwards. Which one of the following graphs correctly represents the velocity vs time?

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The correct option is C

Explanation for correct option:

In case of option $c$:

When a body is thrown vertically upwards, it experiences acceleration due to gravity, $g$ pointing downwards.

The velocity-time formula is

$v=u-gt$…….$\left(i\right)$

The velocity $v$ is a linear function of time $t$. The slope of the velocity-time function gives the acceleration.

Acceleration is negative and constant equal to $-g$.

So, option $c$ is correct.
