Why dont we look at it from another direction !!!

If the treadmill is moving at 60 MPH in one direction and the trust is
set to pull 60 MPH in the oppisite direction, the plane would be
neither moving forward or back.
Why. What's keeping it from moving forward if the thrust is set for a
thrust that would normally move it forward at 60mph. And besides, you
just said that the plane is moving neither forward nor backward. The
statement of the problem is that the conveyor moves at the same rate
and opposite direction as the plane. Since you say the plane is not
moving, I guess neither is the conveyor. Do you really think that is
what the poser of the question intended? g
