A $75$ kg cliff$-$diver is falls from a height through the air head, diving towards the water. The drag coefficient for the diver is $0\mathrm{.}83$ and the area of the descending diver is $0\mathrm{.}21$ m$^2.$ Assuming the density of air is equal to $1\mathrm{.}21$ kg$/$m$^3$:

$($a$)$ Determine the gravitational force acting on the diver.

select units

$($b$)$ Dermine the drag force resisting the motion of the diver at the precise moment in time that the diver falls with a velocity of $83\mathrm{.}54$ m$/$s$.$
