What is the temperature distribution plot of T(x) through the length of the spoon?

The underlying differential equation is
lambda*V*d^2T/dx^2 = alpha*A*(T-T_inf)
with boundary conditions
T(0) = Tb, dT/dx(L) = 0
The solution is
T(x) = T_inf + (Tb-T_inf)*cosh(sqrt(alpha*A/(lambda*V))*(L-x))/cosh(sqrt(alpha*A/(lambda*V))*L)
So the m in your hint is
m = sqrt(alpha*A/(lambda*V))
This should suffice as hint how to plot the temperature profile over x.
