MCQ
An object is moving with a uniform acceleration which is parallel to its instantaneous direction of motion. The displacement $(s) - $ velocity $(v)$ graph of this object is
- A
- B
- ✓
- D
✓
Answer
Correct option: C.
c
(c) ${v^2} = {u^2} + 2aS$, If $u = 0$ then ${v^2} \propto S$
(c) ${v^2} = {u^2} + 2aS$, If $u = 0$ then ${v^2} \propto S$
i.e. graph should be parabola symmetric to displacement axis.
