Could you please post future code snippets as InputForm so that we could
read it?
<< "Graphics`ImplicitPlot`"
u0 = 76;
\[Omega] = Pi/12;
uh = u0/E^(k*t);
up = 7*(5 - 5/E^(k*t) - (1/(k^2 + \[Omega]^2))*
((2*k*((-k)*Cos[3*\[Omega]] + \[Omega]*Sin[3*\[Omega]] +
E^(k*t)*(k*Cos[(-3 + t)*\[Omega]] +
\[Omega]*Sin[(-3 + t)*\[Omega]])))/E^(k*t)));
myANS = uh + up;
U = myANS;
If you like the aspect ratio of the (t,k)-plane in your 3d-plot, you
should assign that plot to a variable
p3d = Plot3D[U, {t, 0, 72}, {k, 0.2, 0.48}];
and extract the option AspectRatio from it:
ImplicitPlot[U == 30, {t, 0, 72}, {k, 0.2, 0.48},
AspectRatio -> (AspectRatio /. AbsoluteOptions[p3d])]
But you can give any number in AspectRatio->(height/width)
