    Given n = 25 Hz

    =>By T = 1/n = 1/25 = 0.04 sec

    Thus by T = 2π√[m/k]

    =>0.04 = 2 x 3.14 x √[1.25/k]

    =>√[1.25/k] = 6.37 x 10^-3

    =>1.25/k = (6.37 x 10^-3)^2

    =>k = 1.25/(6.37 x 10^-3)^2

    =>k = 30811.25 N/m

    Use.

    frequency= sqrt9K/M). K= 25^2*1.25=781.25 N/m

    omega = 2 * pi * frequency = 50pi /sec

    omega = square root of (k/m)

    Substitute and find k
