Question

For velocity – time graph of given figure


The acceleration – time graph of the motion of the body is

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

For $0$ to $3\text{s}$, acceleration is positive as slope of $v-t$ graph is positive.
For $3$ to $5\text{s}$, acceleration is zero as slope of $v-t$ graph is $0$.
From $5$ to $7\text{s}$, acceleration is negative as slope of $v-t$ graph is negative.
Hence, option c is correct.
