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 :
Answer: (A) see figure
Concept. Acceleration is the slope of the $v$–$t$ graph.
Step 1. Read each part of the $v$–$t$ graph.
- $v = 0$: $a = 0$.
- $v$ rises linearly: constant positive $a$.
- $v$ constant: $a = 0$.
- $v$ falls linearly to zero: constant negative $a$.
- $v = 0$ again: $a = 0$.
Step 2. Choose. Zero, a positive step, zero, a negative step, zero: graph (1).
Answer. Graph (1) (Option A).
