An electric aircraft is towing a glider along a straight horizontal flight path at a constant speed.
A constant tension of TTT newtons exists in the horizontal tow-line connecting the aircraft to the glider.
The aircraft's propulsion system provides a constant forward thrust of 3200 N3200 \text{ N}3200 N.
The constant air resistance (drag) acting on the glider is 1150 N1150 \text{ N}1150 N.
Determine the value of TTT, providing a justification based on the physical state of the system.
Identify one assumption made regarding the tow-line in your answer to part (a).
Calculate the magnitude of the drag force acting on the aircraft.
