1) Use Solutions(), not Solve()

ans:Assume(v_{M}>0∧v>0∧0≤θ≤(pi)/(2), Solutions({eq1,eq2},{v,v_{M}}))

2) Define it as a function like

f(m,v_{0},θ,M,R,g):=Element(Element(ans,1),2)

Got it. Thank you very much.

A little problem, it works, but f2() displayed in Algebra area is different from f1().
