# Magnitude homework help

## Homework Statement

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 $$F=ma$$
Fg = 0.125*9.8 which gives the answer 1.225 but am unsure what to do next?
