  • A \(1 ms^{-2}\)
  • B \(2 ms^{-2}\)
  • C \(3 ms^{-2}\)
  • D \(4 ms^{-2}\)
Correct Answer: Option C
Explanation:
The two time differentiation of distance with respect to time will give the acceleration.
\(s = \frac{3}{2}t^{2} - 3t\)
\(\frac{\mathrm d s}{\mathrm d t} = v = 3t - 3\)
\(\frac{\mathrm d v}{\mathrm d t} = a = 3\)
