Yes. A rock falling from a height has negative joules. When a displacement is in the same direction as the force the work is negative and represents exergy, energy out.
I notice that the "exergy" is in red indicating it is not a word recognized by the system.
This is a fundamental question in physics. Energy is energy into a system and is positive, exergy is energy coming out of the system and is negative. Exergy is like explosion and energy is like implosion. Exercise is energy coming out of the body system.

Is it reasonable to have a work output of 150 Joules when work input is 110 Joules?
No. It is not reasonable. If that ever happened, we would have to ask where the additional 40 joules came from, since energy cannot be created or destroyed. If there were something inside the box that added 40 joules to the 110 passing through, then that 40 would need to be added to the "input" work.
