The displacement-time graph of a moving particle with constant acceleration is shown in. The velocity-time is given by
.

Options

A.
B.
C.
D.

Answer

A

Explanation

`From big :-
For time interval `t=0` to `t=1sec`
slope of x-t graph os negative and increasing so velocity increases in negative direction
` For t=1 to 2sec`
The slope is +ve and decreasing so velocity is decreasing in + ve direction and become zero at so (A) is correct
