How can I plot the integral
((2mg)/(2mg-rho*s*Cd*V^2)dv)
from 0 to 61.6318493
m=0.023
g=9.81
rho=1.2
s=0.00011
Cd=0.9

Q = @(x) sym(x);
m = Q(0.023);
g = Q(9.81);
rho = Q(1.2);
s = Q(0.00011);
Cd = Q(0.9);
syms v V real
f =(2 .* m .* g) ./ (2 .* m .* g - rho .* s .* Cd .* v.^2);
F = int(f,0,V)
F = 
fplot(F, [0, 61.6318493])
format long g
boundary = sqrt(125350/33)
boundary =
61.6318493028146
Looks like your upper bound is exactly the boundary after which the integral becomes infinite.
