An object moving along $x$-axis with a uniform acceleration has velocity $\overrightarrow{v}=\left(12 \mathrm{cm} {\mathrm{s}}^{-1}\right) \hat{\mathrm{i}}$ at $x=3 \mathrm{cm}$. After $2 \mathrm{s}$ if it is at $x=-5 \mathrm{cm}$, then its acceleration is,

• Correct answer
  A

  $\overrightarrow{a}=\left(-16 \mathrm{cm} {\mathrm{s}}^{-2}\right) \hat{\mathrm{i}}$
• B

  $\overrightarrow{a}=\left(11 \mathrm{cm} {\mathrm{s}}^{-2}\right) \hat{\mathrm{i}}$
• C

  $\overrightarrow{a}=\left(-11{\mathrm{cms}}^{-2}\right) \hat{\mathrm{i}}$
• D

  $\overrightarrow{a}=\left(8 \mathrm{cm} {\mathrm{s}}^{-2}\right) \hat{\mathrm{i}}$

Hence, the correct answer is option: 'A'.
