Hello to everyone. I need to solve differential equations system and when I run the code, the computation process does not come to an end. How could I fix this problem? Any assistance would be highly appreciated. Thanks a lot.
k = 1230002/10^8;
m = k/(k + 1);
\[Xi] = 1/2 (1 - 2 m);
A = 2/\[Xi];
DSolve[{z2'[
t] == (z2[t]*
Sqrt[4 - (A*z2[t] + 1)^2/3])/(\[Xi]*(A*z2[t] + 1)^1/3),
z2[0] == 7/2*\[Xi]}, z2[t], t]
