A man in a wingsuit glides through the air at a constant velocity of $47\,\text{m s}^{-1}$ at an angle of $24^{\circ}$ to the horizontal, as shown in Fig. 2.1. The combined mass of the man and the wingsuit is $85\,\text{kg}$. He takes $2.8$ minutes to glide from point A to point B. Referring to the man’s motion, state and explain whether he is in equilibrium.
Show that the vertical height difference $h$ between A and B is $3200\,\text{m}$.
For the man’s journey from A to B, determine the decrease in gravitational potential energy.
For the man’s journey from A to B, determine the magnitude of the force on the man due to air resistance.
The pressure of the still air at A is $63\,\text{kPa}$ and at B is $92\,\text{kPa}$. Assume that the air density is constant between A and B. Determine the density of the air between A and B.

For the man’s journey from A to B, determine the magnitude of the force on the man due to air resistance.
The pressure of the still air at A is $63\,\text{kPa}$ and at B is $92\,\text{kPa}$. Assume that the air density does not change between A and B. Determine the density of the air between A and B.
