Physics - NLM Question with Solution | TestHub

We know that$a=\frac{\mathrm{D}\mathrm{i}\mathrm{s}\mathrm{p}\mathrm{l}\mathrm{a}\mathrm{c}\mathrm{e}\mathrm{m}\mathrm{e}\mathrm{n}\mathrm{t}}{{\left(\mathrm{T}\mathrm{i}\mathrm{m}\mathrm{e}\right)}^2}$

$a=\frac{x_2-x_1}{t^2}\mathrm{ }\mathrm{ }\mathrm{ }\mathrm{ }\mathrm{ }\left(\mathrm{i}\mathrm{f}\mathrm{ }{x}_2>x_1\right)$

by Newton's second law of motion

$s=ut+\frac{1}{2}a{t}^2$

Where u = 0 (Body is at rest)

So,$x_1=0+\frac{1}{2}\times \frac{x_2-x_1}{t^2}\times t^2$

$x_1=\frac{x_2-x_1}{2}$

$\Rightarrow 2x_1=x_2-x_1$

$3x_1=x_2$
