medium

The velocity $(v)-$ time $(t)$ plot of the motion of a body is shown below:

(image)

The acceleration $(a)-$ time $(t)$ graph that best suits this motion is :

(NEET-2024)

Solution

Initially, the body has zero velocity and zero slope. Hence the acceleration would be zero initially. After that, the slope of v-t curve is constant and positive.

After some time, velocity becomes constant and acceleration is zero.

After that, the slope of v-t curve is constant and negative.
