Estimate the time that a Gaussian wave packet associated with an electron, which at t=0 is localized to 10^-10 m, doubles its width Assume that the relation omega = (h-bar k^2)/(2 m) holds (omega = 2 pi f = angular frequency).

Plug the values for the constants in yourself. I got:
t = (2)(sqrt(3))(10^-20)(m)/(h-bar)

well i got the answer
s(t) = s0 sqrt(1 + 4 a^2 t^2 / s0^4)
a = 1/2 d^2omega/dk^2 = 1/2 h-bar/m
Solve with s = 2 s0 and you get:
t = sqrt(3/4) (s0^2)/a
i still have no idea how these functions were derived. gah.
