Question

Which of the following velocity time graphs shows a realistic situation for a body in motion?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

We know that any physical body cannot have two different magnitudes of velocity at the same instant. So if you draw a line parallel to velocity line in the graph and if it crosses more than one point, we can say that that graph is unrealistic.

For the graphs $b,c$ and $d$, the graphs turns out to be unrealistic. Hence option $a$ in the only realistic graph here.
