Analyse the stability of the open-loop system. Is the system stable?

The linearized longitudinal motion of a helicopter near hover can be modeled by the following
normalized equations:
=
-0.01] [91 6.3
0 + 8
+
-0.02 u 19.81
[-0.4 0

-1.4 9.8
where q is the pitch rate, is the pitch angle of fuselage,
u is the horizontal velocity, and 8 is the rotor tilt angle,
which corresponds to the control input.
Suppose our sensor measures the horizontal velocity u as
the output.
