Question

we take the air properties as:
ρ=1.225 kg/m3 , μ=1.783∗10−5 kg/( m*s) , c=340.3 m/s

IMPORTANT: I don't need to know about the Dcontainer.
I need help with the S value for the velocity of 4m/s on landing (as specified in the brief)

The task is to parachute supply of 120 kg that includes the containing
circular cylinder case of D=0.4 m and L=2.5m from altitude of
between 300 m to 500 m, while ensuring the supply does not hit the
ground at a speed higher than 4 m/s.
The 1D governing equation of motion is:
dv
m =mg.
dt
S
D
pV²SC₁-D
mg
Terminal velocity is defined when dV/dt=0. You have to decide
whether Dcontainer is important.
