A body is bound to move along a straight line, say X-axis.It is initially at rest at origin.It moves to point (1m,0) in one second and comes to rest. How can we prove that absolute value of acceleration of this particle exceeds 4ms*2 atleast once?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
- Consider a scenario in which the body moves as quickly as possible given the acceleration threshold.
- Does the body reach its goal within the given time?
- Can any body with less acceleration be faster?
