Simple Harmonic Motion oscillations

  • #1
A 0.49 kg mass attached to a spring (k = 19.8 N m-1) is performing SHM on a smooth horizontal surface. Calculate the periodic time of these oscillations, in s.

what equation links with T=2pi/w to give T or how do i use a=-ky/m.
thanks in advance

if
F=ma= m*d^2y/dx^2 = -m*w^2*y = -ky
i get T=0.988

The linking equation you're looking for is:

[tex]k = m\omega^2[/tex]
