Solution


Q.

The velocity (v) – time (t) plot of the motion of a body is shown below.

The acceleration (a) – time (t) graph that best suits this motion is                        [2024]
1  
2  
3  
4  

Ans.

(3)

Slope of velocity-time graph gives acceleration.

AB: Slope is positive and constant, so acceleration is positive and constant.
BC: Slope is zero, so acceleration is zero.
CD: Slope is negative and constant, so acceleration is negative and constant.
