Solution:Here is given, block of mass (m) = 250gm = 250 x 10-3 kgTime (t) = 0.15 secDisplacement (x) = 40cm = 40 x 10-2mFrequency (f) = ?Force constant (k) = ?We know,a.  f  = 1/t = 1/0.15 = 6.67 rev sec-1b. Amplitude (xm) =(frac{40 times 10^{-2}}{2}) = 20 x 10-2 mc. Again we know that(2pi f = sqrt{frac{k}{m}})(4pi^2f^2 = frac{k}{m})(k = 4pi^2f^2 m)(k = 4pi^{2}(6.67)^2 times 250 times 10^{-3})k = 439.08 Nm-1Hence, required frequency, amplitude and force constant are 6.67 rev s-1, 20 x 10-2m and 439.08 Nm-1
