m = 7;
x[t_] = 6 t^4 + t^2;
y[t_] = 3 ArcTan[t] - 1;
z[t_] = 2 t^3 + 1;
F = 140;
eqn = x''[t] m + y''[t] m + z''[t] m;
mySol1 = Reduce[eqn > F && t > 0, t];


t > Root[-3 + #1 + 6 #1^2 + 4 #1^3 + 21 #1^4 + 2 #1^5 + 12 #1^6 &, 2]

How can I get an answer one number?

See the second example in the documentation for Root. If that does not address your question, please clarify. – Michael E2 Dec 19 '14 at 18:29
Try N for a numeric result. – Yves Klett Dec 19 '14 at 18:30
See this recent answer by Mark McClure. It gives some relevant tricks you could use. – Jens Dec 19 '14 at 18:55
