# Q. 14.9 (ii) A spring having with a spring constant $\inline 1200\; N\; m^{-1}$ is mounted on a horizontal table as shown in Fig. 14.24. A mass of $\inline 3\; kg$ is attached to the free end of the spring. The mass is then pulled sideways to a distance of $\inline 2.0\; cm$  and released.Determine(ii) maximum acceleration of the mass, and

$\\a_{max}=\frac{F_{A}}{m}\\ a_{max}=\frac{kA}{m}\\ a_{max}=\frac{1200\times 0.2}{3} \\a_{max}=8ms^{-2}$ (FA = Force experienced by body at displacement A from mean position)
