x = .04 meter

F = m g = 9.81(.1) = .981 N

k = F/x = .981/.04 = 24.5 Newtons/meter

let y = A sin 2 pi t/T

F = -ky = -kA sin 2 pi t/T

v = (2 pi /T)A cos 2 pi t/T

a = - (2 pi/T)^2 A sin 2 pi t/T

F = m a

so

k y = m(2 pi /T )^2 y

2 pi/T = sqrt k/m

T = 2 pi sqrt (m/k)

= 2 pi sqrt (.1/24.5)

= 0.401 seconds
