The displacement-time graph of a body is shown in.
.
The velocity-time graph of the motion of the body will be .

Options

A. .
B. .
C. .
D. .

Answer

D

Explanation

From `0` to `t_(1)`, Verlocity id positive and constant as indicated by positive and constant slope.
From `t_(1)` to `t_(3), slope is zero hence velocty is zero.
From `t_(3)` to `t_(4)` velocity is negative and constant as indicated by negative and constant slope.
Option `d` satisfies all these observations.
