Question

an object starts from rest. write down the changed equation for the motion of the object

Answer 1

First equation of motion- v=at

Second equation of motion- s=1/2 a t(square)

Third equation of motion- v squared= 2as

Answer 2

• let it be 1-D motion then the equation is,

$x_{final} = x_{initial} + v_{initial} ( t) + (1/2) (a)t ^2$

• here is the,

             x is the position coordinate,

             v is velocity,

             t is time,

           and a is acceleration.

• The equation for an object which starts from rest is  $v_{i}$  $o$, $o(t)$  is just $0$.

• So the equation you ask for is

        $x_{final} = x_{initial} + (1/2) (a)t ^2$

answer= $x_{f}=x_{i}+\frac{1}{2} (a)(t^{2})$
