Given ,

The displacement of particle at any time t is

  • S = 4t³ +3t² + 6t + 8

We know that ,

 \large  \boxed{ \sf{Instanteous \:  acceleration  \: (a) =  \frac{ {d}^{2} S}{dt} }}

Thus ,

 \sf \mapsto a = 24t + 6

Put t = 2 , we get

 \sf \mapsto  a = 24 \times 2 + 6 \\  \\  \sf \mapsto  a =54 \:  \: m {s}^{ - 2}

 \sf \therefore{ \underline{The \:  acceleration \:  of \:  the \:  particle \:  at  \: 2  \: sec \:  is \:  54  \: </p><p>m {s}^{ - 2} }}
