There are essentially three forces involved in flying: (i) ``lift'' Fl generated by the difference in air pressure between the top and bottom parts of a wing (or wing-like object), (ii) ``drag'' Fd due to air resistance, and (iii) ``gravity'' Fg. Note that ``lift'' is usually perpendicular to the flight direction while ``drag'' is directed in the opposite direction to flight.
These forces are involved in explaining the flight of aeroplanes, birds, flying foxes (bats), flying fish, sugar gliders, etc. Consider a sugar glider (petaurus breviceps) of mass m = 0.125 kg that is gliding from one tree to the next along a straight path at $ \theta$ = 29.2o with respect to the horizontal as shown in the diagram. Assuming that there is negligible ``drag'', what is the magnitude of the ``lift'' force (in N)?
The Attempt at a Solution
Im unsure where to start. I solved for Fg using [tex]F=ma[/tex]
Fg = 0.125*9.8 which gives the answer 1.225 but am unsure what to do next?
