A particle of mass 0.3 kg is subjected to a force \(F=-k \boldsymbol{x}\) with k = 15 N/m. What will be its initial acceleration if it is released from a point 20 cm away from the origin?
  1. \(5 \mathrm{~m} / \mathrm{s}^{2}\)
  2. \(10 \mathrm{~m} / \mathrm{s}^{2}\)
  3. \(3 \mathrm{~m} / \mathrm{s}^{2}\)
  4. \(15 \mathrm{~m} / \mathrm{s}^{2}\)

Answer

(B) 10 ~m / s ^ 2
