Question

u=16ms^1,v=0,s=0.4m then t=​

Answer 1

${2}^{ - 3}$

$\frac{1}{ {2}^{3} }$

$\frac{1}{2 \times 2 \times 2}$

$\frac{1}{8}$

Answer 2

${ \large{ \bold{ \ GIVEN:-}}} \\ u = 16 \\ v = 0 \\ s = 0 \\ t =? \\ Apply \: 3rd \: equation \: of \: motion \\ {v}^{2} - {u}^{2} = 2as \\ {0}^{2} - {16}^{2} = 2 \times a \times 0 \\ a = \frac{ - 256}{2} \\ a = ( - 128) m \: per \: {s}^{2} \\ Apply \: 1st\: equation \: of \: motion \\ v = u + at \\ 0 = 16 + (- 128 \times t) \\ (- 128 \times t) = - 16 \\ t = \frac{ - 16}{ - 128} \\ t = 0.125 \: s$
