MCQ
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 :
- A
- ✓
- C
- D
✓
Answer
Correct option: B.
b
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.
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.
