If the air resistance is proportional to the square of the velocity, the proportional coefficient is k, and the mass of the satellite is m, then the velocity of the satellite is? The speed is represented by K and m

This can only be solved by using differential equation
f = mg - kv^2
f = m*dv/dt
dv/dt = g - k/m*v^2
The solution is more troublesome, consider for yourself, hee hee
