Here the file with the correct calculation

restart; A0 := 1.2; A := .35; h := 0.45e-1; g := 9.81; eq := -2*A^2*g*h-A^2*v[0]^2+A0^2*v[0]^2 = 0

1.3175*v[0]^2-.108155250 = 0

 (1)

solve(eq, v[0])

.2865157436, -.2865157436

Many thanks for your answer. Here the file (Document Mode).

 

restart; A[0] := 1.2; A := .35; h := 0.45e-1; g := 9.81; eq := -2*A^2*g*h-A^2*v[0]^2+A[0]^2*v[0]^2 = 0

.35[0]^2*v[0]^2-.1225*v[0]^2-.108155250 = 0

 (1)

solve(eq, v[0])

68.67000000/(43600.*.35[0]^2-5341.)^(1/2), -68.67000000/(43600.*.35[0]^2-5341.)^(1/2)
