resistance propotionell to the square of the velecito

Apparently not. Newton's 3rd Law says

F = m dv/dt.

Newtons third law is the princip of action and reaction



If you set 2 v^2 A q = m dv/dt you will find that
dv/dt depends on mass. Your expression for dv/dt does
not depend on mass.


I have made transformation of units .
In the following equation's the unit of distance is
the distance the body must travel to hit a mass of m/2.
the unit of time is choisen to make the gravity=10

v_x'=-00-v_x.|v|


v_y'=-10-v_y.|v|

EARTH'S GRAVITY =10!!!!!!!!!!!!!!!!!!!!!!!!
