Hi,
Could you please have a look on the attachment?
Question 1:
Why is this differential equation non-linear? Is it [itex]u=\overset{\cdot }{m}[/itex] which makes it non-linear?
I think one can consider [itex]x_{3}[/itex] , k, and g to be constants. If it is really [itex]u=\overset{\cdot }{m}[/itex] which makes it non-linear then I don't think it's possible to make it linear. Could you please correct me?
Question 2:
What is there in "These expressions" which shows that the system is linear? Is it "0 x u"?
