hello,(adsbygoogle = window.adsbygoogle || []).push({});

what would be the best way to approach this problem

A skydiver is jumping out of a plane at :

Initial velocity = 100 mph

Initial position = 2000 m

acceleration due to gravity = -9.81

I need help finding air friction at different positions, change in acceleration and change in velocity ?

i think u calculate air friction

A= f * v * v(abs) * cd

A= acceleration

f= atmospheric pressure

v= velocity

s= surface area

cd= drag coefficient
